Pin Configuration
The PTH12000 series of non-isolated
power modules are small in size and high
on performance. Using double-sided surface mount construction and synchronous
rectification technology, these regulators
deliver up to 6 A of output current while
occupying a PCB area of about half the
size of a standard postage stamp. They
are an ideal choice for applications where
space, performance and cost are important design constraints.
The series operates from an input
voltage of 12 V to provide step-down
power conversion to any output voltage
over the range, 1.2 V to 5.5 V. The output voltage of the PTH12000W is set
within this range using a single resistor.
Operating features include an on/off
inhibit, output voltage adjust (trim),
and output over-current protection.
Target applications include telecom,
industrial, and general purpose circuits,
including low-power dual-voltage systems
that use a DSP, microprocessor, or ASIC.
Package options include both throughhole and surface mount configurations.

Pin Descriptions
Vin: The positive input voltage power node to the module, which is referenced to common GND.
Vout: The regulated positive power output with respect
to the GND node.
Inhibit: The Inhibit pin is an open-collector/drain negative
logic input that is referenced to GND. Applying a lowlevel ground signal to this input disables the module’s
output and turns off the output voltage. When the Inhibit
control is active, the input current drawn by the regulator
is significantly reduced. If the Inhibit pin is left opencircuit, the module will produce an output whenever a
valid input source is applied.

ADVANCE INFORMATION
GND: This is the common ground connection for the
‘Vin’ and ‘Vout’ power connections. It is also the 0 VDC
reference for the ‘Inhibit’ and ‘Vo Adjust’ control inputs.
Vo Adjust: A 0.5 %, 0.1 W resistor must be connected
between this pin and the GND pin to set the output
voltage to the desired value. The set point range for the
output voltage is from 1.2 V to 5.5 V. The resistor required
for a given output voltage may be calculated from the
following formula. If left open circuit, the module output will default to its lowest output voltage value. For
further information on the adjustment and/or trimming
of the output voltage, consult the related application note.

Notes: (1) See SOA curves or consult factory for appropriate derating.
(2) The Inhibit control (pin 3) has an internal pull-up to Vin, and if left open-circuit the module will operate when input power is applied. A small lowleakage (<100 nA) MOSFET is recommended to control this input. See application notes for more information.
(3) The regulator requires a minimum of 100 µF input capacitor with a minimum 750 mArms ripple current rating. For further information, consult the
related application note on Capacitor Recommendations.
(4) An external output capacitor is not required for basic operation. Adding 100 µF of distributed capacitance at the load will improve the transient response.

Application Notes
PTH12000 Series
Capacitor Recommendations for the PTH12000
6-A Kestrel Regulator Series
Input Capacitors
The recommended input capacitance is determined by
750 mA (rms) minimum ripple current rating, less than
150 mΩ equivalent series resistance (ESR) and 100 µF
minimum capacitance. The ripple current rating, ESR,
and operating temperature are the major considerations
when selecting the input capacitor.
Tantalum/ Ceramic Capacitors
Tantalum capacitors are acceptable on the output bus.
Either tantalum or Os-con® capacitor types are recommended for applications where ambient temperatures
fall below 0 °C. Electrolytic capacitors may be substituted
with ceramic types with the minimum capacitance on the
input bus.
It is recommended that tantalum capacitors have a minimum voltage rating of at least twice the working voltage,
including the ac ripple. This is necessary to insure reliability with 12-V input voltage bus applications. Only
one tantalum capacitor (68 µF, 25 V) was found to meet
this requirement.
Capacitor Table
Table 2-1 identifies capacitors with acceptable ESR and
maximum allowable ripple current (rms) ratings. Capacitors recommended for the output are identified under
the Output Bus column with the required quantity.
This is not an extensive capacitor list. Capacitors from other
vendors are available with comparable specifications. Those
listed are for guidance. The RMS ripple current rating and
ESR (at 100 kHz) are critical parameters necessary to insure
both optimum regulator performance and long capacitor life.
Output Capacitors (Optional)
The ESR of the required capacitor can be less than, or
equal to 150 mΩ. Electrolytic capacitors have poor ripple
performance at frequencies greater than 400 kHz but
excellent low frequency transient response. Above the
ripple frequency, ceramic decoupling capacitors are
necessary to improve the transient response and reduce
any high frequency noise components apparent during
higher current excursions. Preferred low ESR type
capacitor’s part numbers are identified in the capacitor
table.
