AP1501A-33T5L-U集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

AP1501A-33T5L-U属于集成电路（IC）的稳压器-DC-DC开关稳压器。由美台半导体制造生产的AP1501A-33T5L-U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。

General Description

The AP1501A series are monolithic ICs that are designed for a step-down DC/DC converter, and possess the ability to drive a 5A load without additional transistor component. Due to reducing

the number of external component, the board space can be saved easily. The external shutdown function can be controlled by logic level and then come into standby mode.

•150Khz +15 fixed switching frequency

• Voltage mode non-synchronous PWM control

•Thermal-shutdown and current-limit protection

• ON/OFF shutdown control input

• Operating voltage can be up to 40V

• Output load current: 5A

• Low power standby mode

• Built-in switching transistor on chip

• Lead Free packages: TO263-5L and TO220-5L(R)

• TO263-5L and TO220-5L(R): Available in “Green” Molding Compound (No Br, Sb)

• Lead Free Finish/ RoHS Compliant (Note 1)

Applications

• Simple High-efficiency step-down regulator

• On-card switching regulators

• Positive to negative converter
