TPS60302 单节至 3.0V/3.3V、20mA 双路输出、高效充电泵
TPS60302 描述
The TPS6030x 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.
