FAN5601

Regulated Step-Down Charge Pump DC/DC Converter

Features

Description

■ > 85% Peak Efﬁciency

The FAN5601 is an advanced third generation switched capaci-

tor step down DC/DC converter utilizing Fairchild’s proprietary

ScalarPump™ technology. This innovative architecture utilizes

scalar switch re-conﬁguration and fractional switching tech-

niques to produce low output ripple, low ESR spikes and

improve efﬁciency over a wide load range.

■ Low EMI

■ Low Ripple

■ Output Voltage 1.3V/1.8V

■ Input Voltage Range: 2.2V to 5.5V

■ Output Current: Up to 250mA

The FAN5601 produces a ﬁxed regulated output from 2.2V to

5V input voltage. Customized output voltages are available in

100mV increments from 1V to 1.8V. Contact marketing for cus-

tomized outputs.

■

2.5% Output Voltage Accuracy

■ 30µA Operating Current

■ I < 1µA in Shutdown Mode

■ 2MHz Operating Frequency

In order to maximize efﬁciency, the FAN5601 achieves

regulation by skipping pulses. Depending upon load current, the

size of the switches is scaled dynamically, consequently, current

spikes and EMI are minimized. An internal soft start circuitry

prevents excessive current drawn from the supply. The device is

internally protected against short circuit and over temperature

conditions.

■ Shutdown Isolates Output from Input

■ Soft-Start Limits Inrush Current

■ Short Circuit and Over Temperature Protection

■ Minimum External Component Count

■ 6-Lead 3x3mm MLP Package

The FAN5601 is available in 6-lead 3x3mm MLP.
