FAN53526中文资料3.0A，2.4MHz，可数字编程的 TinyBuck® 稳压器数据手册ONSEMI规格书

描述 Description

The FAN53526 is a step-down switching voltage regulator that delivers a digitally programmable output from an input voltage supply of 2.5V to 5.5V. The output voltage is programmed through an I2C interface capable of operating up to 3.4MHz.Using a proprietary architecture with synchronous rectification, the FAN53526is capable of delivering 3.0A continuous at over 80% efficiency, maintaining that efficiency at load currents as low as 10mA. The regulator operates at a nominal fixed frequency of 2.4MHz, which reduces the value of the external components. Additional output capacitance can be added to improve regulation during load transients without affecting stability. At moderate and light loads, Pulse Frequency Modulation (PFM) is used to operate in Power-Save Mode with a typical quiescent current of 50μAat room temperature. Even with such a low quiescent current, the part exhibits excellent transient response during large load swings. At higher loads, the system automatically switches to fixed-frequency control, operating at 2.4MHz. In Shutdown Mode, the supply current drops below 1μA, reducing power consumption. PFM Mode can be disabled if fixed frequency is desired. The FAN53526is available in a 15-bump, 1.310mmx 2.015mm, 0.4mm ball pitch WLCSP.

简介

FAN53526属于集成电路（IC）的稳压器-DC-DC开关稳压器。由制造生产的FAN53526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。
