NCP1595中文资料Synchronous Buck Regulator, 1 MHz, 1.5 A数据手册ONSEMI规格书

描述 Description

The NCP1595A is a current mode PWM buck converter with integrated power switch and synchronous rectifier. It can provide up to 1.5A output current with high conversion efficiency. High frequency PWM control scheme can provide a low output ripple noise. Thus, it allows the usage of small size passive components to reduce the board space. In a low load condition, the controller will automatically change to PFM mode which provides a higher efficiency at low load.The NCP1595A is pin to pin compatible to the 2A NCP1597A.
