DESCRIPTION
The UC384xB family of control ICs provides the necessary features to implement off-line or DC to DC fixed frequency current mode control schemes with a minimal external parts count. Internally implemented circuits include a trimmed oscillator for precise DUTY CYCLE CONTROL under voltage lockout featuring start-up current less than 0.5mA, a precision reference trimmed for accuracy at the error amp input, logic to insure latched operation, a PWM comparator which also provides current limit control, and a totem pole output stage designed to source or sink high peak current. The output stage, suitable for driving N-Channel MOSFETs, is low in the offstate.
● TRIMMED OSCILLATOR FOR PRECISE FREQUENCY CONTROL
● OSCILLATOR FREQUENCY GUARANTEED AT 250kHz
● CURRENT MODE OPERATION TO 500kHz
● AUTOMATIC FEED FORWARD COMPENSATION
● LATCHING PWM FOR CYCLE-BY-CYCLE CURRENT LIMITING
● INTERNALLY TRIMMED REFERENCE WITH UNDERVOLTAGE LOCKOUT
● HIGH CURRENT TOTEM POLE OUTPUT
● UNDERVOLTAGE LOCKOUT WITH HYSTERESIS
● LOW START-UP AND OPERATING CURRENT
