The TPS6205x devices are a family of high-efficiency synchronous step-down DC-DC converters that are ideally suited for systems powered from a 1- or 2-cell Li-Ion battery or from a 3- to 5-cell NiCd, NiMH, or alkaline battery.

The TPS6205x devices are synchronous pulse width modulation (PWM) converters with integrated N- and P-channel power MOSFET switches. Synchronous rectification increases efficiency and reduces 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 850 kHz, allowing the use of small inductor and capacitor values. The device can be synchronized to an external clock signal in the range of 600 kHz to 1.2 MHz. For low noise operation, the converter can be programmed into forced-fixed frequency in PWM mode. In shutdown mode, the current consumption is reduced to less than 2 µA. The TPS6205x devices are available in the 10-pin (DGS) micro-small outline package (MSOP) and operates over a free air temperature range of –40°C to 85°C.
