Product Summary

The UC3845AD Current Mode PWM Controller is a pin for pin compatible improved version of the UC3842/3/4/5 family. Providing the necessary features to control current mode switched mode power supplies, this UC3845AD has the following improved features. Start up current is guaranteed to be less than 0.5mA. Oscillator discharge is trimmed to 8.3mA. During under voltage lockout, the output stage can sink at least 10mA at less than 1.2V for VCC over 5V.

Parametrics

UC3845AD absolute maximum ratings: (1)Supply Voltage (Low Impedance Source): 30V; (2)Supply Voltage (ICC mA): Self Limiting; (3)Output Current: ±1A; (4)Output Energy (Capacitive Load): 5μJ; (5)Analog Inputs (Pins 2, 3): -0.3V to +6.3V; (6)Error Amp Output Sink Current: 10mA; (7)Power Dissipation at TA ≤ 25℃ (DIL-8): 1W; (8)Storage Temperature Range: -65℃ to +150℃; (9)Lead Temperature (Soldering, 10 Seconds): 300℃.

Features

UC3845AD features: (1)Optimized for Off-line and DC to DC Converters; (2)Low Start Up Current (<0.5mA); (3)Trimmed Oscillator Discharge Current; (4)Automatic Feed Forward Compensation; (5)Pulse-by-Pulse Current Limiting; (6)Enhanced Load Response Characteristics; (7)Under-Voltage Lockout With Hysteresis; (8)Double Pulse Suppression; (9)High Current Totem Pole Output; (10)Internally Trimmed Bandgap Reference; (11)500kHz Operation; (12)Low RO Error Amp.
