Description
- DESCRIPTION
- The UC1842/3/4/5 family of control ICs 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. The output stage, suitable for driving N Channel MOSFETs, is low in the off state.
- FEATURES
- • Optimized For Off-line And DC To DC Converters
- • Low Start Up Current (<1mA)
- • Automatic Feed Forward Compensation
- • Pulse-by-pulse Current Limiting
- • Enhanced Load Response Characteristics
- • Under-voltage Lockout With Hysteresis
- • Double Pulse Suppression
- • High Current Totem Pole Output
- • Internally Trimmed Bandgap Reference
- • 500khz Operation
- • Low ROError Amp
