UC2844BD1013TR - Brand New STMicroelectronics AC DC Converters, Offline Switchers
-
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 -
