SC2620
Key Features
- Its switching frequency can be programmed up to 1.4MHz per channel
- Due to the SC2620’s high frequency operation, small inductors and ceramic capacitors can be used, resulting in very pact power supplies
- The two channels of the SC2620 operate at 180° out of phase for reduced input voltage ripples
- Separate soft start/enable pins allow independent control of each channel
- Channel 1 power good indicator can be used for output start up sequencing to prevent latch-up
- Current-mode PWM control achieves fast transient response with simple loop pensation
- Cycle-by-cycle current limiting and hiccup overload protection reduce power dissipation during overload
