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 :

components

Applications:

1. ECONOMICAL OFF-LINE FLYBACK OR FORWARD CONVERTERS.

2. DC-DC BUCK OR BOOST CONVERTERS.

3. LOW COST DC MOTOR CONTROL.
