AP1604A

PWM/PFM DUAL MODE STEP-DOWN DC/DC

CONVERTER

General Description

Features

The AP1604 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.

•

Input voltage range: 2.2V~5.5V (V_OUTtype)

Oscillator frequency: 600KHz (Typ.)

Internal reference: 1.0V (Typ.)

High efficiency: 93% (Typ.)

Stand-by capability: I_STB=2µA. (Typ.)

Soft-start time set-up externally type possible

Current limit and thermal shutdown protection

Packages: SOT25-5L

Lead Free Finish/RoHS Compliant for Lead Free and

“Green” products (Note 1)

Output voltage is set-up by the external resistors. (±2.5%

accuracy). The 600KHz AP1604 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 efficiency for both light loads and large

output current.

•

SOT25-5L: Available in “Green” Molding Compound

(No Br, Sb)

AP1604 can be soft-start with a proper capacitor connected

between CE/SS pin and ground. The stand-by current is less

than 2uA when CE/SS pin is at “LOW” status. The device is

forced to switch off as the voltage at that pin is lower than the

stipulated voltage.

Applications

•

Electronic Information Organizers

Palmtops

Cellular and portable phones

Portable Audio Systems

Various Multi-function Power Supplies
