UTC3842
Overview
The UTC3842 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 1mA,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.
- Optimized for off-line and DC to DC converts *Low start up current(<1mA) *Automatic feed forward compensation *Pulse-by-Pulse current limiting *Enhanced load response characteristics *Under-voltage lockout with hysteresis
