LT3685
Overview
The LT®3685 is an adjustable frequency (200kHz to 2.4MHz) monolithic step-down switching regulator that accepts input voltages up to 38V operating and 60V maximum. An internal overvoltage protection circuit turns off the power switch when VIN is above 38V typical (36V minimum) which then allows the part to safely withstand 60V transients.
- Wide Input Range: Operation From 3.6V to 36V Overvoltage Lockout Protects Circuit through 60V Transients
- 2A Maximum Output Current
- Adjustable Switching Frequency: 200kHz to 2.4MHz
- Low Shutdown Current: IQ < 1µA
- Integrated Boost Diode
- Synchronizable Between 250kHz to 2MHz
- Power Good Flag
- Saturating Switch Design: 0.25 On-Resistance
- 0.790V Feedback Reference Voltage
- Output Voltage: 0.79V to 20V
