HIGH PERFORMANCE
CURRENT MODE CONT ROLLER
DES CRIPT ION
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
* Under voltage lockout with hysteresis
* Over voltage protection
* Latching PWM for Cycle-By-Cycle current limiting
* Internally trimmed reference with undervoltage lockout
*Pb-free plating product number:
