Description

The TPS6235x device is a high-frequency synchronous step-down dc-dc converter optimized for battery-powered portable applications. Intended for low-power applications, the TPS6235x supports up to 800-mA load current and allows the use of small, low cost inductors and capacitors.

The device is ideal for mobile phones and similar portable applications powered by a single-cell Li-Ion battery. With an output voltage range adjustable via I²C interface down to 0.6 V, the device supports low-voltage DSPs and processors core power supplies in smart-phones, PDAs, and handheld computers.

The TPS6235x operates at 3-MHz fixed switching frequency and enters the efficiency optimized power-save mode operation at light load currents to maintain high efficiency over the entire load current range.
