TPS60312 单节至 3.3V 20mA 超低静态电流充电泵
TPS60312 描述
The TPS6031X step-up, regulated charge pumps generate a 3-V ±4% or 3.3-V ±4% output voltage from a 0.9-V to 1.8-V input voltage (one alkaline, NiCd, or NiMH battery).
Only five small 1-uF ceramic capacitors are required to build a complete high-efficiency dc/dc charge pump converter. To achieve the high efficiency over a wide input voltage range, the charge pump automatically selects between a 3x or 4x conversion mode.
Output 1 (OUT1) can deliver a maximum of 40 mA, from a 1-V input, with output 2 (OUT2) not loaded. OUT2 can deliver a maximum of 20 mA, from a 1-V input, with OUT1 not loaded. Both outputs can be loaded at the same time, but the total output current of the first voltage doubler must not exceed 40 mA.
