ADP3050:  200 kHz, 1 A Step-Down High-Voltage Switching Regulator

Product Details


Newer Alternatives:
  • ADP2441 36 V,1 A, Synchronous, Step-Down DC-DC Regulator
  • ADP2442 36 V,1 A, Synchronous, Step-Down, DC-to-DC Regulator with External Clock Synchronization

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 and BENEFITS

  • 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
