CURRENT MODE PWM CONTROLLER (KNOWN GOOD DIE)

The UC1843 family of control devices 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 under-voltage lockout featuring start up current less than 1 mA, 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 off state. The under-voltage lockout threshold is 8.4 V and maximum duty cycle range is around 100%. By Texas Instruments
