Description
The UC1845AAY family of control ICs provides all the necessary features to implement off-line fixed-frequency, current-mode switching power supplies with a minimum of external components. The current mode architecture demonstrates improved load regulation, pulse-by-pulse current limiting and inherent protection of the power supply output switch.
Features
1. OPTIMIZED FOR OFF-LINE AND DC-TO-DC CONVERTERS.
2. AUTOMATIC FEED FORWARD COMPENSATION.
3. PULSE-BY-PULSE CURRENT LIMITING.
4. ENHANCED LOAD RESPONSE CHARACTERISTICS.
5. UNDER-VOLTAGE LOCKOUT WITH HYSTERESIS.
Absolute maximum ratings :
Applications:
1. ECONOMICAL OFF-LINE FLYBACK OR FORWARD CONVERTERS.
2. DC-DC BUCK OR BOOST CONVERTERS.
3. LOW COST DC MOTOR CONTROL.
