TPS62050DGS

Импульсный понижающий DC-DC стабилизатор, регулируемый, 2.7В-10В (Vin), 700мВ-6В, 0.8А, VSSOP-10.

The TPS62050DGS is a high-efficiency synchronous step-down DC-to-DC Converter 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 device is synchronous pulse width modulation (PWM) converter 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 850kHz, allowing the use of small inductor and capacitor values. The device can be synchronized to an external clock signal in the range of 600kHz to 1.2MHz. 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 2µA.
