UC3825 General Description
In addition, the UC3825 incorporates an under-voltage lockout mechanism with 800mV of hysteresis, guaranteeing a safe start-up process and minimizing current draw during initial operation. During under-voltage lockout, the outputs are switched to high impedance mode, providing an added layer of protection
Key Features
- Under-Voltage Lockout with Hysteresis
- Pulse-by-Pulse Overcurrent Protection up to 3A
- Dual Outputs with Independent Shutdowns and Enable
- Fault-Tolerant Operation up to 1.5 Failures
- Soft Start / Max. Duty Cycle Control up to 2kHz
- Automatic Recovery from Transient Faults up to 50V
