AP1609

PWM/PFM Dual Mode Step-up DC/DC Converter

Features

General Descriptions

- Input Voltage Range: 2.5~6V

The AP1609 is 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.

- Output Voltage Range: 3.0~17V（±2.5%）

- PWM/PFM Switching Control

- Oscillator Frequency: 300KHz（±20%）

- High Efficiency: 91%（Typ .）

- Stand-by Current: I_STB＝1µA.（Typ.）

- Built-in internal N-Channel MOS

- Pb-Free Package: SOP-8L/TSSOP-8L

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

is highly efficient from light loads to large output

currents.

Applications

- Electronic Information Organizers

- Palmtops

- Cellular and portable phones

- Portable Audio Systems

- Various Multi-function Power Supplies

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

consumption is reduced to 1µA.
