TPS60313

illustrate

The TPS6031X boost-regulated charge pump generates an output voltage from 0.9 to 4% of 3-V to 4±% or 3.3-V to ± 4% of an output voltage of 1.8 V (an alkaline, NiCd or NiMH battery).

Only five small 1 uF ceramic capacitors require a complete high efficiency DC/DC charge pump converter. To achieve high efficiency over a wide input voltage range, the conversion mode between 3x or 4x of the charge pump is automatically selected.

Output 1 (Output 1) provides 40 mA maximum, from 1 - V input to Output 2, (OUT2) is not loaded. OUT2 can provide 20 mA maximum, from 1-V input, without loading OUT1. Two outputs can be loaded at the same time, but the first current of the total output voltage multiplier cannot exceed 40 mA.
