The PS1401 compact, high-efficiency, step-up DC-DC converters are available in tiny, 3-pin thin SOT23 packages. They feature an extremely low 1. 5micro-A 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, these devices are 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. All three devices feature a 0. 5 N-channel power switch. The PS1401 also feature proprietary noise-reduction circuitry, which suppresses electromagnetic interference (EMI) caused by the inductor in many step-up applications. The family offers different combinations of fixed outputs, shutdown, and EMI reduction (see Selector Guide) .
