MCP16252 - PFM/PWM Synchronous Boost Regulator

Download the MCP16252 datasheet PDF. This datasheet also covers the MCP16251 variant, as both devices belong to the same pfm/pwm synchronous boost regulator family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • Up to 96% Typical Efficiency.
  • 650 mA Typical Peak Input Current Limit: - IOUT > 100 mA @ 3.3V VOUT, 1.2V VIN - IOUT > 250 mA @ 3.3V VOUT, 2.4V VIN - IOUT > 225 mA @ 5.0V VOUT, 3.3V VIN.
  • Low Device Quiescent Current: - Output Quiescent Current: < 4 µA typical,  device is not switching (VOUT > VIN, excluding feedback divider current) - Input Sleep Current: 1 µA - No Load Input Current: 14 µA typical.
  • Shutdown Current: 0.6 µA typical.
  • Low Start-Up Volt.
