Description
The FAN48610 is a low-power boost regulator designed to
provide a minimum voltage-regulated rail from a standard
single-cell Li-Ion battery and advanced battery chemistries.
Even below the minimum system battery voltage, the device
maintains the output voltage regulation for a minimum output
load current of 1.0 A. The combination of built-in power
transistors, synchronous rectification, and low supply current
suit the FAN48610 for battery-powered applications.
The FAN48610 is available in a 9-bump, 0.4 mm pitch,
Wafer-Level Chip-Scale Package (WLCSP).

Description
Output Voltage. This pin is the output voltage terminal; connect directly to COUT.
Input Voltage. Connect to Li-Ion battery input power source and the bias supply for the gate drivers.
Switching Node. Connect to inductor.
Enable. When this pin is HIGH, the circuit is enabled.
Power Ground. This is the power return for the IC. COUT capacitor should be returned with the shortest
path possible to these pins.
Analog Ground. This is the signal ground reference for the IC. All voltage levels are measured with
respect to this pin – connect to PGND at a single point.
