LT3579/LT3579-1

6A Boost/Inverting

DC/DC Converter with Fault Protection

FEATURES

DESCRIPTION

The

3579

is a PWM DC/DC converter with built-in fault

protection features to aid in protecting against output shorts,

input/output overvoltage, and overtemperature conditions.

The part consists of a 42V master switch, and a 42V slave

switch that can be tied together for a total current limit of 6A.

The LT3579 is ideal for many local power supply designs. It

can be easily configured in Boost, SEPIC, Inverting, or Flyback

configurations, and is capable of generating 12V at 1.7A, or

–12V at 1.2A from a 5V input. In addition, the LT3579’s slave

switch allows the part to be configured in high voltage, high

power charge pump topologies that are very efficient and

require fewer components than traditional circuits.

The LT3579’s switching frequency range can be set bet-

ween 200kHz and 2.5MHz. The part may be clocked inter-

nally at a frequency set by the resistor from the RT pin to

ground, or it may be synchronized to an external clock.

A buffered version of the clock signal is driven out of

the CLKOUT pin, and may be used to synchronize other

compatible switching regulator ICs to the LT3579.

The LT3579 also features innovative

SHDN

pin circuitry

that allows for slowly varying input signals and an adjust-

able undervoltage lockout function. Additional features

such as frequency foldback and soft-start are integrated.

The LT3579 is available in 20-lead TSSOP and 20-pin

4mm

5mm QFN packages.
