AP1609

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

General Description

Features

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.

•

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: I_STB1 = µA (Typ.)

Built-in internal N-Channel MOS

Lead-Free and Green Package: SOP-8L

Lead Free Finish/RoHS Compliant for Lead Free

products (Note 1)

Output voltage is programmable with 1.23V of standard voltage

supply internal, and using externally connected components,

output voltage (FB) can be set up at will.

With a 300KHz switching frequency, the size of the external

components can be reduced. Control switches from PFM to PWM

during light loads with the AP1609 (PWM/PFM switchable) and

the series are highly efficient from light loads to large output

currents.

During stand-by time (CE pin “Low”), current consumption is

reduced to 1µA.
