SM74202

100V Current Mode PWM Controller

General Description

Features

The SM74202 high voltage pulse-width-modulation (PWM)

controller contains all of the features needed to implement

single ended primary power converter topologies. Output volt-

age regulation is based on current-mode control, which eases

the design of loop compensation while providing inherent line

feed-forward. The SM74202 includes a high-voltage start-up

regulator that operates over a wide input range up to 100V.

The PWM controller is designed for high speed capability in-

cluding an oscillator frequency range to 1MHz and total prop-

agation delays less than 100ns. Additional features include

an error amplifier, precision reference, line under-voltage

lockout, cycle-by-cycle current limit, slope compensation,

softstart, oscillator synchronization capability and thermal

shutdown. The controller is available in the MSOP-10 pack-

age.
