Overview
Features AP1604A PWM/PFM DUAL MODE STEP-DOWN DC/DC CONVERTER General Description • Input voltage range: 2.
2V~5.
5V (VOUT type) • Oscillator frequency: 600KHz (Typ.
) • Internal reference: 1.
0V (Typ.
) • High efficiency: 93% (Typ.
) • Stand-by capability: ISTB=2µA.
(Typ.
) • Soft-start time set-up externally type possible • Current limit and thermal shutdown protection • Lead Free Package: SOT25 • SOT25: Available in “Green” Molding Compound (No Br, Sb) • Lead Free Finish/ RoHS Compliant (Note 1) The AP1604A series are multi-functional step-down DC/DC converters with built-in speed, low ON resistance drivers.
It is capable to deliver more than 800mA output current with external coil, diode and capacitor.
Output voltage is set-up by the external resistors.
(±2.
5% accuracy).
The 600KHz AP1604A that can work out with small value external components comes out more compact board.
The device switches to and works under PFM mode with light loads.
It keeps at high effici...
