LINEAR INTEGRATED CIRCUIT

HIGH PERFORMANCE

CURRENT MODE CONTROLLER

■

DESCRIPTION

The UTC UC3842G of high performance current mode

controller is specifically designed for off-line and DC-to-DC converter

applications offering the designer a cost effective solution with

minimal external components. This integrated circuit features

approximately 300µA start up current, a precision reference trimmed

the error amplifier input. Also included are protective features

consisting of input and reference undervoltage lockouts each with

hysteresis, cycle-by-cycle current limiting, and so on.

■

FEATURES

* Low startup and operating current

* User defined switching frequency(Norm is 52kHz)

* Power-saving mode for low power

*Pb-free plating product number:

UC3842GL

* Under voltage lockout with hysteresis

* Over voltage protection

* Latching PWM for Cycle-By-Cycle current limiting

* Internally trimmed reference with undervoltage lockout
