Description
The IR3447A is an easy-to-use, fully integrated dc - dc Buck regulator. The onboard PWM controller and MOSFETs
with integrated bootstrap diode make IR3447A a small footprint solution, providing high-efficiency power
delivery. Furthermore, it uses a fast Constant On-Time (COT) control scheme, which simplifies design efforts and
provides fast control response.
The IR3447A has an internal low dropout voltage regulator, allowing operation with a single supply. It can also
operate with an external bias supply, extending the operating input voltage (PVIN) range. The IR3447A offers a
switching frequency of 600 kHz, two selectable current limits, soft start time of 2 ms, and Forced Continuous
Conduction Mode (FCCM).
It also features important protection functions, such as pre-bias start-up, thermally compensated current limits,
over voltage and under voltage protection, and thermal shutdown to give required system level security in the
event of fault conditions.
IR3447AMTRPBF属于集成电路(IC) > 稳压器 - DC-DC 开关稳压器。英飞凌科技公司制造生产的IR3447AMTRPBF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。
