LM2716

Dual (Step-up and Step-down) PWM DC/DC Converter

General Description

Features

n Fixed buck converter with a 1.8A, 0.16Ω, internal switch

n Adjustable boost converter with a 3.6A, 0.12Ω, internal

switch

The LM2716 is composed of two PWM DC/DC converters. A

buck (step-down) converter is used to generate a fixed out-

put voltage. A boost (step-up) converter is used to generate

an adjustable output voltage. Both converters feature low

R_DSON(0.16Ω and 0.12Ω) internal switches for maximum

efficiency. Operating frequency can be adjusted anywhere

between 300kHz and 600kHz allowing the use of small

external components. External soft-start pins for each en-

ables the user to tailor the soft-start times to a specific

application. Each converter may also be shut down indepen-

dently with its own shutdown pin. The LM2716 is available in

a low profile 24-lead TSSOP package.

n Adjustable boost output voltage up to 20V

n Operating input voltage range of 4V to 20V

n Input undervoltage protection

n 300kHz to 600kHz pin adjustable operating frequency

n Over temperature protection

n Small 24-Lead TSSOP package

n Patented current limit circuitry

Applications

n TFT-LCD Displays

n Handheld Devices

n Portable Applications

n Cellular Phones/Digital Camers
