AP1625

PWM/PFM Dual Mode Step-down DC/DC Controller

Features

General Descriptions

The AP1625 series are multi-functional step-down

DC/DC converters with built-in speed, low ON

resistance drivers. A more than 1A output current is

possible using an externally connected transistor,

coil, diode and capacitor.

- Input voltage range:2.2V~8V（V_OUTtype）

- Adjustable version（±2.5%）

- Oscillator frequency: 270KHz（±15%）

- High Efficiency: 92%（typ .）

- Stand-by capability: I_STB＝3µA.（max .）

- Soft-start time set-up externally type possible

- Output voltage type possible（FB）

- Package: SOT23-5

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

accuracy）.

With a 270KHz switching frequency, the size of the

external components can be reduced.

Control switches from PWM to PFM during light

loads with the AP1625（PWM/PFM switchable）and

the series is highly efficient from light loads to large

output currents.

Applications

● Electronic Information Organizers

● Palmtops

In relation to soft-start time external capacitor

regulated types.

● Cellular and portable phones

● Portable Audio Systems

● Various Multi-function Power Supplies

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

consumption is reduced to less than 0.5µA.

With U.V.L.O internal, the external MOSFET. Will

be forcibly switched off if used below the stipulated

voltage.
