ST619集成电路（IC）稳压器-DC-DC开关稳压器规格书PDF中文资料

DESCRIPTION

The ST619LB is a step-up charge pump DC-DC converter which delivers a regulated 5V ±4 output at 30mA and over temperature. The input voltage range is 2V to 3.6V (two battery cells). It requires only four external capacitor: two 0.22µF flying capacitors, and 10µF capacitors at the input and output.

■ REGULATED 5V ±4 CHARGE PUMP

■ OUTPUT CURRENT GUARANTEED OVER TEMPERATURE : 20mA (VI ≥ 2V ), 30mA (VI ≥ 3V )

■ NO INDUCTORS; VERY LOW EMI NOISE

■ USES SMALL, INEXPENSIVE CAPACITORS

■ LOGIC CONTROLLED 1µA MAX SHUT-DOWN SUPPLY CURRENT

■ SHUT DOWN DISCONNECTS LOAD FROM INPUT

■ AVAILABLE IN SO-8 AND DIP-8 PACKAGES

ST619属于集成电路（IC） > 稳压器 - DC-DC 开关稳压器。意法半导体（ST）集团制造生产的ST619稳压器 - DC-DC 开关稳压器DC-DC 开关稳压器 PMIC（电源管理集成电路）产品族中的产品是元器件级设备，用于需要稳定 DC 输入电压和/或将其转换为不同幅度的输出电压的应用。这些器件与称为“控制器”PMIC 的类似产品的区别在于集成了主开关元件，设备提供的电力会通过该元件。
