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 40μA 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
* Under voltage lockout with hysteresis
* Over voltage protection
* Latching PWM for Cycle-By-Cycle current limiting
* Internally trimmed reference with undervoltage lockout
