DESCRIPTION

The TSM006 integrated circuits incorporate all

circuitry to implement off line or DC-DC power

supply applications using a fixed frequency

current mode control.

Based

on

a

standard

current

mode

PWM

controller,

these

devices

include

additional

features for higher integration.
