直流/直流固定充电泵, 电压转换器, 2.7 V至5.5 V输入, 1.9 V至50 mA输出, µMAX-10
The is a 50mA regulated step-down charge pump for 1.8V or 1.9V logic in 10 pin µMAX package. This charge pump generates up to 50mA at fixed output voltages of 1.8V or 1.9V. It is specifically designed to provide high efficiency logic supplies in applications that demand a compact design, it employs fractional conversion techniques to provide efficiency exceeding that of a linear regulator. It operates at up to 2MHz, permitting use of small 0.22µF flying capacitors while maintaining low 75µA quiescent supply current. Proprietary soft-start circuitry prevents excessive current from being drawn from the supply during startup, making IC compatible with higher impedance sources such as alkaline and lithium-ion cells. It is used in low-voltage logic supplies, wireless handsets, PDAs and PC cards.
