Description

The PTH12000 series of non-isolated

power modules are small in size and high

on performance. Using double-sided sur-

face 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 impor-

tant design constraints.

The series operates from an input volt-

age of 12 V to provide step-down power

conversion to a wide range of output volt-

ages. W-suffix devices are adjustable from

1.2 V to 5.5 V, and L-suffix devices are

adjustable from 0.8 V to 1.8 V. The out-

put voltage is set within the adjustment

range using a single external resistor.

Operating features include an on/off

inhibit, output voltage adjust (trim), and

the ability to start up into an existing

output voltage or prebias. A non-latching

over-current trip provides protection

against load faults.

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 through-

hole and surface mount configurations.

Application Notes PTH12000 Series Capacitor Recommendations for the PTH12000 Wide-Output Adjust Power Modules Input Capacitor The recommended input capacitance is determined by the 100 μF minimum capacitance and 750 mArms minimum ripple current rating. A 10-μF X5R/X7R ceramic capacitor may also be added to reduce the reflected input ripple current [3]. The ceramic capacitor should be located between the input electrolytic and the module.

Application Notes PTH12000 Series Adjusting the Output Voltage of the PTH12000x Wide-Output Adjust Power Modules The Vo Adjust control (pin 4) sets the output voltage of the PTH12000 product. The adjustment range is from 1.2 V to 5.5 V for the W-suffix modules, and 0.8 V to 1.8 V for L-suffix modules. The adjustment method requires the addition of a single external resistor, R set, that must be connected directly between the Vo Adjust and GND pins 1.

Application Notes PTH12000 Series Power-Up Characteristics When configured per the standard application, the PTH12000x power modules produce a regulated output voltage whenever of a valid input voltage is applied from Vin (pin 2), with respect to GND (pin 1). During the power-up period, internal soft-start circuitry slows the rate that the output voltage rises. This reduces the in-rush current drawn from the input source.
PAGE 12
Application Notes PTH12000 Series Pre-Bias Startup Capability The capability to start up into an output pre-bias condition is now a feature of the PTH12000 series of modules. (Note: This is a feature enhancement for the the W-suffix version; see note 1). the Inhibit pin is held low, and whenver the output is allowed to rise under soft-start control.
