Step−Down Converter
The NCP9001 step−down PWM DC−DC converter is optimized for
portable applications powered from one cell Li−ion or three cell
Alkaline/NiCd/NiMH batteries. The device is available in an adjustable
output voltage from 0.9 V to 3.3 V. It uses synchronous rectification to
increase efficiency and reduce external part count. The device also has a
built−in 1.5 MHz (nominal) oscillator which reduces component size by
allowing a small inductor and capacitors. Automatic switching
PWM/PFM mode offers improved system efficiency.
Finally, it includes an integrated soft−start, cycle−by−cycle current
limiting, and thermal shutdown protection. The NCP9001 is
available in the space saving, low profile TSOP5 package.

NCP9001
OPERATION DESCRIPTION
Overview
The NCP9001 uses a constant frequency, current mode
step−down architecture. Both the main (P−Channel
MOSFET) and synchronous (N−Channel MOSFET)
switches are internal.
It delivers a constant voltage from either a single Li−Ion
or three cell NiMH/NiCd battery to portable devices such
as cell phones and PDA. The output voltage is set by the
external resistor divider. The NCP9001 sources at least
600 mA, depending on external components chosen.
The NCP9001 works with two modes of operation;
PWM/PFM depending on the current required. The device
operates in PWM mode at load currents of approximately
40 mA or higher, having voltage tolerance of "3% with
90% efficiency or better. Lighter load currents cause the
device to automatically switch into PFM mode for reduced
current consumption (IQ = 30 mA typ) and extended battery
life.
Additional features include soft−start, undervoltage
protection, current overload protection, and thermal
shutdown protection. As shown in Figure 1, only six
external components are required for implementation. The
part uses an internal reference voltage of 0.6 V. It is
recommended to keep the part in shutdown until the input
voltage is 2.7 V or higher.

Figure 23. PWM Switching Waveform
(Vin = 3.6 V, Vout = 1.8 V, Iout = 300 mA)
PFM Operating Mode
Under light load conditions (<40 mA), the NCP9001
enters in low current PFM mode operation to reduce power
consumption. The output regulation is implemented by
pulse frequency modulation. If the output voltage drops
below the threshold of PFM comparator (typically
Vnom−2%), a new cycle will be initiated by the PFM
comparator to turn on the switch Q1. Q1 remains ON until
the peak inductor current reaches 200 mA (nom). Then
ILIM comparator goes high to switch off Q1. After a short
dead time delay, switch rectifier Q2 is turned ON. The
negative current detector (NCD) will detect when the
inductor current drops below zero and sends the signal to
turn off Q2. The output voltage continues to decrease
through discharging the output capacitor. When the output
voltage falls below the threshold of the PFM comparator,
a new cycle starts immediately.
PWM Operating Mode
In this mode, the output voltage of the NCP9001 is
regulated by modulating the on−time pulse width of the
main switch Q1 at a fixed frequency of 1.5 MHz. The
switching of the PMOS Q1 is controlled by a flip−flop
driven by the internal oscillator and a comparator that
compares the error signal from an error amplifier with the
sum of the sensed current signal and compensation ramp.
At the beginning of each cycle, the main switch Q1 is
turned ON by the rising edge of the internal oscillator
clock. The inductor current ramps up until the sum of the
current sense signal and compensation ramp becomes
higher than the error voltage amplifier. Once this has
occurred, the PWM comparator resets the flip−flop, Q1 is
turned OFF and the synchronous switch Q2 is turned ON.
Q2 replaces the external Schottky diode to reduce the
conduction loss and improve the efficiency. To avoid
overall power loss, a certain amount of dead time is
introduced to ensure Q1 is completely turned OFF before
Q2 is being turned ON.

NCP9001
Cycle−by−Cycle Current Limitation
consumption will be 0.3 mA (typical value). Applying a
voltage above 1.2 V to EN pin will enable the device for
normal operation. The typical threshold is around 0.7 V.
The device will go through soft−start to normal operation,
however, the EN pin should be tied low while the input
voltage on VIN pin is rising up.
From the block diagram (Figure 3), an ILIM comparator
is used to realize cycle−by−cycle current limit protection.
The comparator compares the LX pin voltage with the
reference voltage, which is biased by a constant current. If
the inductor current reaches the limit, the ILIM comparator
detects the LX voltage falling below the reference voltage
and releases the signal to turn off the switch Q1. The
cycle−by−cycle current limit is set at 1200 mA (nom).
Thermal Shutdown
Internal Thermal Shutdown circuitry is provided to
protect the integrated circuit in the event that the maximum
junction temperature is exceeded. If the junction
temperature exceeds 160_C, the device shuts down. In this
mode switch Q1 and Q2 and the control circuits are all
turned off. The device restarts in soft−start after the
temperature drops below 135_C. This feature is provided
to prevent catastrophic failures from accidental device
overheating, and it is not intended as a substitute for proper
heatsinking.
Short Circuit Protection
When the output is shorted to ground, the device limits
the inductor current. The duty−cycle is minimum and the
consumption on the input line is 300 mA (Typ). When the
short circuit condition is removed, the device returns to the
normal mode of operation.
Soft−Start
The NCP9001 uses soft−start (300 ms Typ) to limit the
inrush current when the device is initially enabled.
Soft−start is implemented by gradually increasing the
reference voltage until it reaches the full reference voltage.
During startup, a pulsed current source charges the internal
soft−start capacitor to provide gradually increasing
reference voltage. When the voltage across the capacitor
ramps up to the nominal reference voltage, the pulsed
current source will be switched off and the reference
voltage will switch to the regular reference voltage.
Low Dropout Operation
The NCP9001 offers a low input to output voltage
difference. The NCP9001 can operate at 100% duty cycle.
In this mode the PMOS (Q1) switches completely on.
The minimum input voltage to maintain regulation can
be calculated as:
VIN(min) + VOUT(max)
) (IOUT (RDS(on) ) RINDUCTOR))
(eq. 1)
•

•
•
Shutdown Mode
When the EN pin has a voltage applied of less than 0.4 V,
the NCP9001 will be disabled. In shutdown mode, the
internal reference, oscillator and most of the control
circuitries are turned off. Therefore, the typical current

APPLICATION INFORMATION
Output Voltage Selection
The corner frequency is given by:
The output voltage is programmed through an external
resistor divider connected from VOUT to FB then to GND.
For low power consumption and noise immunity, the
resistor from FB to GND (R2) should be in the
[100 k−600 k] range. If R2 is 200 k given the VFB is 0.6 V,
the current through the divider will be 3.0 mA.
The formula below gives the value of VOUT, given the
desired R1 and the R1 value:

(eq. 3)
The device is intended to operate with inductance values
between 1.0 mH and maximum of 4.7 mH.
If the corner frequency is moved, it is recommended to
check the loop stability depending on the output ripple
voltage accepted and output current required. For lower
frequency, the stability will be increased; a larger output
capacitor value could be chosen without critical effect on
the system. On the other hand, a smaller capacitor value
increases the corner frequency and it should be critical for
the system stability. Take care to check the loop stability.
The phase margin is usually higher than 45°.

Table 2. L−C Filter Example
Input Capacitor Selection
In PWM operating mode, the input current is pulsating
with large switching noise. Using an input bypass capacitor
can reduce the peak current transients drawn from the
input supply source, thereby reducing switching noise
significantly. The capacitance needed for the input bypass
capacitor depends on the source impedance of the input
supply.
The maximum RMS current occurs at 50% duty cycle
with maximum output current, which is IO, max/2.
For NCP9001, a low profile, low ESR ceramic capacitor
of 4.7 mF should be used for most of the cases. For effective
bypass results, the input capacitor should be placed as close
as possible to the VIN pin.

Output L−C Filter Design Considerations
The NCP9001 is built in 1.5 MHz frequency and uses
current mode architecture. The correct selection of the
output filter ensures good stability and fast transient
response.
Due to the nature of the buck converter, the output L−C
filter must be selected to work with internal compensation.
For NCP9001, the internal compensation is internally fixed
and it is optimized for an output filter of L = 2.2 mH and
COUT = 10 mF.
(eq. 5)
DIL(MAX) Maximum inductor current
DIO(MAX) Maximum Output current
The inductor’s resistance will factor into the overall
efficiency of the converter. For best performances, the DC
resistance should be less than 0.3 W for good efficiency.

ESR values will have the lowest output ripple voltage and
are strongly recommended. The output capacitor requires
either an X7R or X5R dielectric.
The output ripple voltage in PWM mode is given by:
DVOUT + DIL

Feed−Forward Capacitor Selection
The feed−forward capacitor sets the feedback loop
response and is critical to obtain good loop stability.
Given that the compensation is internally fixed, a fixed
18 pF or higher ceramic capacitor is needed. Choose a
small ceramic capacitor X7R or X5R or COG dielectric.

) ESR (eq. 6)
In PFM mode (at light load), the output voltage is
regulated by pulse frequency modulation. The output
voltage ripple is independent of the output capacitor value.
It is set by the threshold of PFM comparator.
