The FAN5601 is a regulated step-down charge pump DC/DC converter with features including > 85% peak efficiency, low EMI, low ripple, output voltage range of 1.3V/1.8V, input voltage range of 2.2V to 5.5V, output current up to 250mA, ±2.5% output voltage accuracy, 30µA operating current, Icc < 1µA in shutdown mode, 2MHz operating frequency, short circuit and over temperature protection, etc.
The FAN5601 is a third‑generation switched‑capacitor step‑down DC/DC converter that uses Fairchild’s ScalarPump™ technology. It delivers a fixed regulated output voltage with low ripple, low EMI, and high efficiency across a wide load range. The device includes internal soft‑start, short‑circuit, and over‑temperature protection, and its shutdown mode isolates the output from the input.
Typical applications include handheld computers, cell phones, digital cameras, and core supply for next‑generation processors. The part is offered in a 6‑lead 3 × 3 mm MLP package and supports output voltages of 1.3 V or 1.8 V with up to 250 mA of output current.
