UC3845BD1013TR-STMICROELECTRONICS-UC3845BD1013TR-PWM CONTROLLER, 500KHZ, 0 TO 70DEG C

UC3845BD1013TR is a high performance current mode PWM controller. This control IC 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. This device has UVLO thresholds of 10V (off), ideally suited off-line applications.
