MB39C014集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

MB39C014属于集成电路（IC）的稳压器-DC-DC开关稳压器。由赛普拉斯半导体公司制造生产的MB39C014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。

描述 Description

The MB39C014 is a current mode type 1-channel DC/DC converter IC built-in switching FET, synchronous rectification, and down conversion support. The device is integrated with a switching FET, oscillator, error amplifier, PWM control circuit, reference voltage source, and POWERGOOD circuit.

External inductor and decoupling capacitor are needed only for the external component.

As combining with external parts enables a DC/DC converter with a compact and high load response characteristic, this is suitable as the built-in power supply for such as mobile phone/PDA, DVDs, and HDDs.
