UC3842AL-S08-T

CURRENT MODE PWM CONTROL CIRCUITS

DESCRIPTION

The UC3842A/3843A provide the necessary functions to implement off-line or DC to DC fixed frequency current mode, controlled switching circuits with minimal external components.

FEATURES

*Low start up current Typical 0.12mA

*Automatic feed forward compensation

*Pulse-by-Pulse current limiting

*Under-voltage lockout with hysteresis

*Double pulse Suppression

*High current totem pole output to drive MOSFET directly

*Internally trimmed band gap reference

*500kHz operation
