HM6291 - boost DC-DC converter

General Description

The HM6291 is a current mode boost DC-DC converter.

Its PWM circuitry with built-in 0.2Ω power MOSFET make this regulator highly power efficient.

The internal compensation network also minimizes as much as 6 external component counts.

Key Features

  • Adjustable Output up to 12V.
  • Internal Fixed PWM frequency: 1.2MHz.
  • Precision Feedback Reference Voltage: 0.6V (±2%).
  • Internal 0.2Ω, 2A, 18V Power MOSFET.
  • Shutdown Current: 0.1μA.
  • Over Temperature Protection.
  • Adjustable Over Current Protection: 0.5A ~ 2.5A.
  • Package: SOT23-6L.

HM6291 General Description The HM6291 is a current mode boost DC-DC converter. Its PWM circuitry with built-in 0.2Ω power MOSFET make this regulator highly power efficient. The internal compensation network also minimizes as much as 6 external component counts. The non-inverting input of error amplifier connects to a 0.6V precision reference voltage and internal soft -start function can reduce the inrush current. The HM6291 is available in the SOT23-6L package and provides space-saving PCB for the application fields.
