STOD1412屬于集成電路（IC）的穩(wěn)壓器-DC-DC開關(guān)穩(wěn)壓器。由意法半導體集團制造生產(chǎn)的STOD1412穩(wěn)壓器 - DC-DC 開關(guān)穩(wěn)壓器DC-DC 開關(guān)穩(wěn)壓器 PMIC（電源管理集成電路）產(chǎn)品族中的產(chǎn)品是元器件級設備，用于需要穩(wěn)定 DC 輸入電壓和/或?qū)⑵滢D(zhuǎn)換為不同幅度的輸出電壓的應用。這些器件與稱為“控制器”PMIC 的類似產(chǎn)品的區(qū)別在于集成了主開關(guān)元件，設備提供的電力會通過該元件。

描述 Description

The STOD1412 is a dual DC-DC converter capable of providing a positive and negative voltage from a positive input voltage ranging from 2.7 V to 5.5 V. It integrates two complete power stages, one step-up and one inverting, each of which need just one inductor, and input and output capacitor.

特性 Features

■ 2.7 V to 5.5 V input voltage range

■ 120 mA max output current for each converter

■ Output voltages:

– Step-up from 4.3 V to 6.0 V

– Inverting from -8.0 V to -2.0 V

■ Synchronous rectification for both DC-DC converters

■ Efficiency:

– 80 IO = 10 mA - 30 mA

– 85 IO = 30 mA - 120 mA

■ 1.3 MHz PWM mode control

■ Shutdown mode with Enable pin

■ Inrush current protection

■ Adjustable output voltages

■ True shutdown mode

■ Less than 1 μA current consumption in shutdown mode

■ Over-temperature protection

■ Package: 16 pin - QFN 3X3

■ Temperature range: -40°C to 85°C

Applications

■ Active matrix organic LED power supplies

■ Mobile phones

■ PDAs

■ Camcorders

■ Digital still cameras
