AP1609 - PWM/PFM DUAL MODE STEP-UP DC/DC CONVERTER

General Description

The AP1609 is a high efficient step-up DC/DC converter.

Large output current is possible having a built in internal N channel MOSFET, and using an external coil and diode.

Key Features

  • Input Voltage Range: 2.5~6V.
  • Output Voltage Range: 3.0~17V (±2.5%).
  • PWM/PFM Switching Control.
  • Oscillator Frequency: 300KHz (±20%).
  • High Efficiency: 91% (Typ. ).
  • Stand-by Current: ISTB 1 = µA (Typ. ).
  • Built-in internal N-Channel MOS.
  • Lead Free Package: SOP-8L.
  • SOP-8L: Available in “Green” Molding Compound (No Br, Sb).
  • Lead Free Finish/ RoHS Compliant (Note 1) General.
