Description

The TPS6200x devices are a family of low-noise synchronous step-down dc-dc converters that are ideally suited for systems powered from a 1-cell Li-ion battery or from a 2- to 3-cell NiCd, NiMH, or alkaline battery. The TPS6200x operates typically down to an input voltage of 1.8 V, with a specified minimum input voltage of 2 V.

The TPS6200x is a synchronous current-mode PWM converter with integrated — and P-channel power MOSFET switches. Synchronous rectification is used to increase efficiency and to reduce external component count. To achieve the 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 750 kHz, allowing the use of small inductor and capacitor values. The device can be synchronized to an external clock signal in the range of 500 kHz to 1 MHz. For low-noise operation, the converter can be operated in the PWM mode and the internal antiringing switch reduces noise and EMI. In the shutdown mode, the current consumption is reduced to less than 1 µA. The TPS62000 is available in the 10-pin (DGS) microsmall outline package (MSOP). The device operates over a free-air temperature range of -40°C to 85°C.
