LM5022

60V Low Side Controller for Boost and SEPIC

General Description

Features

The LM5022 is a high voltage low-side N-channel MOSFET

controller ideal for use in boost and SEPIC regulators. It con-

tains all of the features needed to implement single ended

primary topologies. Output voltage regulation is based on

current-mode control, which eases the design of loop com-

pensation while providing inherent input voltage feed-forward.

The LM5022 includes a start-up regulator that operates over

a wide input range of 6V to 60V. The PWM controller is de-

signed for high speed capability including an oscillator fre-

quency range up to 2 MHz and total propagation delays less

than 100 ns. Additional features include an error amplifier,

precision reference, line under-voltage lockout, cycle-by-cy-

cle current limit, slope compensation, soft-start, external syn-

chronization capability and thermal shutdown. The LM5022 is

available in the MSOP-10 package.
