DC-DC开关升压稳压器, 可调, 1.2V-5.5V输入, 2V-5.5V/150输出, TSOT-5

The from Products is a 1.5µA IQ, step-up DC to DC converter in 5 pin TSOT package. Features an extremely low 1.5µA quiescent supply current to ensure the highest possible light-load efficiency. Optimized for operation from one to two alkaline or nickel-metal-hydride NiMH cells or a single Li+ cell, device is ideal for applications where extremely low quiescent current and ultra-small size are critical. Built-in synchronous rectification significantly improves efficiency and reduces size and cost by eliminating the need for an external Schottky diode. The device features a 0.5ohm N-channel power switch. Typical applications include pagers, remote controls, remote wireless transmitters, personal medical devices, digital still cameras, single-cell battery-powered devices, low-power hand-held instruments, MP3 players and personal digital assistants PDA.
