Additional Information
Step-Down Switching Voltage RegulatorsMilitary Qualified
The LT1076MK is a monolithic bipolar switching regulator. This device is rated at 2A and requires only a few external parts for operation. The power switch, all oscillator and control circuitry, and all current limit components, are included on the chip. This switching regulator can be used several different ways, such as a positive-to-negative converter, a negative boost converter, or a flyback converter.
Features:
- 100kHz Switching Frequency
- Greatly Improved Dynamic Behavior
- Only 8.5mA Quiescent Current
- Operates up to 45V Input
- Micropower Shutdown
