ADP3050: 200 kHz, 1 A Step-Down High-Voltage Switching Regulator
Product Description
The ADP3050 is a current-mode monolithic buck (step-down) PWM switching regulator that contains a high current 1A switch and all control, logic and protection functions. It uses a unique compensation scheme which allows the use of any type of output capacitor (tantalum, ceramic, electrolytic, OS-CON). Unlike some buck regulators, the design is not restricted to using a specific type of output capacitor or ESR value.
Features
- Wide Input Voltage Range: 3.6 V to 30 V
- Adjustable and Fixed (3.3 V, 5 V) Output Options
- Integrated 1 A Power Switch
- Uses Small Surface-Mount Components
- Cycle-By-Cycle Current Limiting
- Peak Input Voltage (100 ms): 60 V
- Thermally Enhanced 8-Lead
SOIC Package - Configurable as a Buck,
Inverter and SEPIC Regulator
