LM2717-ADJ

Dual Step-Down DC/DC Converter

General Description

Features

n Adjustable buck converter with a 2.2A, 0.16Ω, internal

switch (Buck 1)

The LM2717-ADJ is composed of two PWM DC/DC buck

(step-down) converters. Both converters are used to gener-

ate an adjustable output voltage as low as 1.267V. Both also

feature low R_DSON(0.16Ω) 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 con-

verter enables the user to tailor the soft-start times to a

specific application. Each converter may also be shut down

independently with its own shutdown pin. The LM2717-ADJ

is available in a low profile 24-lead TSSOP package ensur-

ing a low profile overall solution.

n Adjustable buck converter with a 3.2A, 0.16Ω, internal

switch (Buck 2)

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

Applications

n TFT-LCD Displays

n Handheld Devices

n Portable Applications

n Laptop Computers

n Automotive Applications
