Description

The TPS62110 is a low-noise synchronous step-down dc-dc converter that is ideally suited for systems powered from a 2-cell Li-ion battery or from a 12-V or 15-V rail.

The TPS62110 is a synchronous PWM converter with integrated N-channel and P-channel power MOSFET switches. Synchronous rectification is used to increase efficiency and to reduce external component count. To achieve highest efficiency over a wide load current range, the converter enters a power-saving, pulse-frequency modulation (PFM) mode at light load currents. Operating frequency is typically 1 MHz, allowing the use of small inductor and capacitor values. The device can be synchronized to an external clock signal in the range of 0.8 MHz to 1.4 MHz. For low noise operation, the converter can be operated in PWM-only mode. In the shutdown mode, the current consumption is reduced to less than 2 µA. The TPS62110 is available in the 16-pin (PWP) QFP package, and operates over a free-air temperature range of –55°C to 175°C.
