The TC120 consumes only 55A (max) of supply
current (VOUT = 3.3V) and can be placed in shutdown
mode by bringing the shutdown input (SHDN) low.
During shutdown, the regulator is disabled, supply
current is reduced to 2.5A (max), and VOUT is
internally pulled to ground, discharging the output
capacitor. Normal operation resumes when SHDN is
brought high. Other features include a built-in undervoltage lockout (UVLO), an externally programmable
soft start time, and output short circuit protection. The
TC120 operates from a maximum input voltage of 10V
and is available in a low-profile 8-Pin SOP package.

EXT
TC120 is a 300kHz PFM/PWM step-down (Buck) DC/
DC regulator/controller combination for use in systems
operating from two or more cells, or in line-powered
applications. It uses PWM as the primary modulation
scheme, but automatically converts to PFM at low
output loads for greater efficiency. It requires only an
external inductor, Schottky diode, and two capacitors to
implement a step-down converter having a maximum
output current of 600mA (VIN = 5V, VOUT = 3.3V). An
external switching transistor (P-channel MOSFET) can
be added to increase output current capability to
support output loads of 2A or more.

Extended external switching transistor drive output. This output follows the timing on the EXT
output with an additional 100nsec blanking time on both the leading and trailing edges. That is,
this output transitions from high-to-low 100 nsec prior to the same transition on EXT; and
transitions low-to-high 100nsec after the same transition on EXT; resulting in a longer external
switch ON time. (See Section 3.9 External Switching Transistor Selection).

SHDN/SS
Shutdown and soft-start control input. A soft start capacitor of 100pF (min) must be connected to
this input. The soft start capacitor is charged by an internal A current source that gently ramps
the TC120 into service. Shutdown control is best implemented with an external open collector (or
open drain) switch. The TC120 enters shutdown when this input is low. During shutdown, the
regulator is disabled, and supply current is reduced to less than 2.5A. Normal operation is
restored when this input is open-circuited, and allowed to float high. (See Section 3.6 Low Power

DETAILED DESCRIPTION
3.2
The TC120 can be operated as an integrated stepdown regulator (using the internal switching transistor);
or as a step-down regulator controller (using an
external switching transistor). When operating as an
integrated regulator, the only required external components are a Schottky diode, inductor and an output
capacitor. Operating in this configuration, the TC120 is
capable of supporting output load currents to a
maximum of 600mA with operating efficiencies above
85%. Efficiencies at high loads can be further improved
by using the on-board charge pump circuit to pull the
gate of the internal switching transistor below ground
for the lowest possible ON resistance. (For more information, see Section 3.5 Improving High Load
Efficiency in Regulator Operating Mode).
Higher output currents are achieved by operating the
TC120 with an external P-channel switching transistor
(controller mode). In this operating configuration, the
maximum output current is determined primarily by the
ON resistance of the P-channel switch and the series
resistance of the inductor.

3.1
Inductor Selection
Selecting the proper inductor value is a trade-off
between physical size and power conversion requirements. Lower value inductors cost less, but result in
higher ripple current and core losses. They are also
more prone to saturate since the coil current ramps
faster and could overshoot the desired peak value. This
not only reduces efficiency, but could also cause the
current rating of the external components to be
exceeded. Larger inductor values reduce both ripple
current and core losses, but are larger in physical size
and tend to increase the start-up time slightly. A 22H
inductor is the best overall compromise and is recommended for use with the TC120. For highest efficiency,
use inductors with a low DC resistance (less than
20m). To minimize radiated noise, consider using a
toroid, pot core or shielded-bobbin inductor.
 2001-2012 Microchip Technology Inc.
Input Bypass Capacitor
Using an input bypass capacitor reduces peak current
transients drawn from the input supply, and reduces the
switching noise generated by the regulator. The source
impedance of the input supply determines the size of
the capacitor that should be used.
3.3
Output Capacitor
The effective series resistance of the output capacitor
directly affects the amplitude of the output voltage
ripple. (The product of the peak inductor current and
the ESR determines output ripple amplitude.) Therefore, a capacitor with the lowest possible ESR should
be selected. Smaller capacitors are acceptable for light
loads or in applications where ripple is not a concern. A
47F Tantalum capacitor is recommended for most
applications. The Sprague 595D series of tantalum
capacitors are amongst the smallest of all low ESR
surface mount capacitors available. Table 3-1 lists
suggested components and suppliers.
3.4
Catch Diode
The high operating frequency of the TC120 requires a
high-speed diode. Schottky diodes such as the MA737
or 1N5817 through 1N5823 (and the equivalent surface
mount versions) are recommended. Select a diode
whose average current rating is greater than the peak
inductor current; and whose voltage rating is higher
than VINMAX.
3.5
Improving High Load Efficiency in
Regulator Operating Mode
If the TC120 is operated at high output loads most (or
all) of the time, efficiency can be improved with the
addition of two components. Ordinarily, the voltage
swing on the gate of the internal P-channel transistor is
from ground to VIN. By adding a capacitor and diode as
shown in Figure 3-2, an inverting charge pump is
formed, enabling the internal gate voltage to swing
from a negative voltage to +VIN. This increased drive
lowers the RDSON of the internal transistor, improving
efficiency at high output currents. Care must be taken
to ensure the voltage measured between VIN and CPC
does not exceed an absolute value of 10V. While this is
not a problem at values of VIN at (or below) 5V, higher
VIN values will require the addition of a clamping
mechanism (such as a Zener diode) to limit the voltage
as described. While this technique improves efficiency
at high output loads, it is at the expense of low load
efficiency because energy is expended charging and
discharging the charge pump capacitor. This technique
is therefore not recommended for applications that
operate the TC120 at low output currents for extended
time periods. If unused, CPC must be grounded.
DS21365C-page 5
TC120
3.6
Low Power Shutdown Mode/Soft
Start Input
The SHDN/SS input acts as both the shutdown control
and the node for the external soft start capacitor, which
is charged by an internal 1A current source. A value
of 4700pF (100pF minimum) is recommended for the
soft start capacitor. Failure to do this may cause large
overshoot voltages and/or large inrush currents resulting in possible instability. The TC120 enters a low
power shutdown mode when SHDN/SS is brought low.
While in shutdown, the oscillator is disabled and the
output discharge switch is turned on, discharging the
output capacitor. Figure 3-3 shows the recommended
interface circuits to the SHDN/SS input. As shown, the
SHDN/SS input should be controlled using an open
collector (or open drain) device, such that the SHDN/
SS input is grounded for shutdown mode, and opencircuited for normal operation (Figure 3-3a). If a CMOS
device is used to control shutdown (Figure 3-3b), the
value of R1 and CSS should be chosen such that the
voltage on SHDN/SS rises from ground to 0.65V in
1.5msec (Figure 3-4). If shutdown is not used, CSS
must still be connected as shown in Figure 3-3c and
Figure 3-3d. SHDN/SS may be pulled up with a resistor
(Figure 3-3c) as long as the values of RSS and CSS
provide the approximate charging characteristic on
power up shown in Figure 3-4. CSS only may also be
connected as shown in Figure 3-3d with CSS chosen at
4700pF (minimum 100pF).
3.7
Undervoltage Lockout (UVLO)
The TC120 is disabled whenever VIN is below the
undervoltage lockout threshold. This threshold is equal
to the guaranteed minimum operating voltage for the
TC120 (i.e., 2.2V). When UVLO is active, the TC120 is
completely disabled.
3.8
3.9
External Switching Transistor
Selection
EXT is a complimentary output with a maximum ON
resistances of 32 to VDD when high and 26 to
ground when low, at VOUT = 5V. It is designed to
directly drive a P-channel MOSFET (Figure 3-5). The
P-channel MOSFET selection is determined mainly by
the on-resistance, gate-source threshold and gate
charge requirements. Also, the drain-to-source and
gate-to-source breakdown voltage ratings must be
greater than VINMAX. The total gate charge specification
should be less than 100nC for best efficiency. The
MOSFET must be capable of handling the required
peak inductor current, and should have a very low onresistance at that current. For example, a Si9430
MOSFET has a drain-to-source rating of -20V, and a
typical on-resistance rDSON of 0.07 at 2A, with VGS =
-4.5V. (EXTW (Figure 3-6) may be gated with external
circuitry to add blanking, or as an auxiliary timing
signal.) Table 3-1 lists suggested components and
suppliers.
3.10
Board Layout Guidelines
As with all inductive switching regulators, the TC120
generates fast switching waveforms, which radiate
noise. Interconnecting lead lengths should be
minimized to keep stray capacitance, trace resistance
and radiated noise as low as possible. In addition, the
GND pin, input bypass capacitor and output filter
capacitor ground leads should be connected to a single
point. The input capacitor should be placed as close to
power and ground pins of the TC120 as possible. The
length of the EXT trace must also be kept as short as
possible.
Short Circuit Protection
Upon detection of an output short circuit condition, the
TC120 reduces the PWM duty cycle to a minimum
value using its internal protection timer. The sequence
of events is as follows: when an output voltage
decrease to near zero is detected (as the result of an
overload), the internal (5msec) protection timer is
started. If the output voltage has not recovered to
nominal value prior to the expiration of the protection
timer, the TC120 is momentarily shut down by
dedicated, internal circuitry. Immediately following this
action, the soft start sequence is engaged in an attempt
to re-start the TC120. If the output short circuit is
removed, normal operation is automatically restored. If
the short circuit is still present, the timed self-shutdown
sequence described above is repeated.
