The TPS61070DDCR is a 90% efficient synchronous boost converter with 600-mA Switch. It provides a power supply solution for products powered by either a one-cell, Input two-cell, or three-cell alkaline, NiCd or NiMH, or one-cell Li-ion or Li-polymer battery. Output currents can go as high as 75 mA while using a single-cell alkaline, and discharge it down to 0.9 V. The TPS61070DDCR can also rail or a Li-ion battery. The boost converter is based on a fixed frequency, pulse-width-modulation (PWM) controller using a synchronous rectifier to obtain maximum efficiency. The applications of the TPS61070DDCR include Portable Audio Players, PDAs, Cellular Phones, Personal Medical Products, White LED Lighting.
