FAN5631/FAN5632 is a regulated step down charge pump DC/DC converter with features including 90% peak efficiency, low EMI, low ripple, selectable output voltage, input voltage range of 2.2V to 5.5V, maximum output current of 250mA, etc.
The FAN5631 and FAN5632 are regulated step‑down charge‑pump DC/DC converters that operate from 2.2 V to 5.5 V input and deliver up to 250 mA. They feature high peak efficiency (up to 90 %), low EMI, selectable output voltages (1.2 V/1.5 V for FAN5631) and an efficiency‑optimizer mode for FAN5632.
The devices are supplied in a 10‑lead 3 × 3 mm MLP package, include internal soft‑start, short‑circuit and over‑temperature protection, and are intended for portable electronics such as cell phones, handheld computers and digital cameras.
| Peak Efficiency | 90 % |
|---|---|
| Maximum Output Current | 250 mA |
| Operating Ambient Temperature Range | -40 °C to +85 °C |
| Package | 10‑lead 3 × 3 mm MLP |
Both devices include short‑circuit protection, over‑temperature protection, and shutdown isolation of the output from the input.
They are offered in a 10‑lead 3 × 3 mm molded lead‑less package (MLP).
