Description

The FAN5631/FAN5632 is an advanced, third-generation switched capacitor step-down DC/DC converter utilizing Fairchild's proprietary ScalarPump™ technology. This innovative architecture utilizes scalar switch re-configuration and fractional switching techniques to produce low output ripple, lower ESR spikes, and improve efficiency over a wide load range.

The FAN5631/FAN5632 produces a fixed regulated output voltage from an input voltage of 2.2V to 5V. Customized output voltages are available in 100mV increments from 1V to 1.8V.

Contact a Fairchild sales representative for customized output voltage options.

In order to maximize efficiency, the FAN5631/5632 achieves regulation by skipping pulses. Depending upon load current, the size of the switches are 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.

The FAN5631 has a dual output voltage feature. When VSEL is high, VOUT is 1.5V and when VSEL is low, VOUT is 1.2V. Other output voltage options are available upon request.

In addition, the FAN5632 has an efficiency optimizer feature that, when enabled, changes the switch mode configuration from 2:1 to 1:1 at the lower threshold of VIN.

The efficiency is then maintained at its peak level over a wider range of input voltages. In addition, VOUT will vary between 1.2V to 1.5V as a result of this efficiency optimization. If the efficiency optimizer is not enabled, VOUT is regulated to 1.5V.

Both the FAN5631 and FAN5632 are available in a 3x3mm 10-lead MLP package.
