UC3842AN規(guī)格書詳情
DESCRIPTION
The UC384xA family of control ICs provides the necessary features to implement off-line or DC to DC fixed frequencycurrent mode control schemes with a minimal external parts count. Internally implemented circuits includea trimmed oscillator for precise DUTY CYCLE CONTROL under voltage lock out featuring start-up current less than0.5mA,a precision reference trimmed for accuracy at the error amp input,logic to in sure latched operation,a PWM comparator which also provides current limit control, and a totem pole output stage designed to source or sink high peakcurrent.The output stage,suitable
for driving N-Channel MOSFETs, is low in the off state.
. TRIMMED OSCILLATOR DISCHARGE CURRENT
. CURRENT MODE OPERATION TO 500kHz
. AUTOMATIC FEED FORWARD COMPENSATION
. LATCHING PWM FOR CYCLE-BY-CYCLECURRENT LIMITING
. INTERNALLY TRIMMED REFERENCE WITH UNDERVOLTAGE LOCKOUT
. HIGH CURRENT TOTEM POLE OUTPUT
. UNDERVOLTAGE LOCKOUT WITH HYSTERESIS
. LOW START-UP CURRENT (< 0.5mA)
. DOUBLE PULSE SUPPRESSION
