2.5A输出电流4.75V至20V电源电压CXSD62377固定500kHz开关频率电流模式Buck-PWM转换器内置P沟道功率MOSFET

The CXSD62377 is a high efficiency, 2.5A buck converter with a high-side low RDS(ON) switch. It operates from 4.75V to 20V input voltage range, and provides up to 2.5A continuous output current with the output voltage adjustable down to 1.2V. Whenever the load is light, the CXSD62377 automatically change the PWM operation mode to PFM operation to minimize the power consumption. Hence it is suitable for battery-powered devices. It uses a fixed switching frequency up to 500kHz. When a short circuit is detected on the output, the device change switching frequency to 50kHz to protect IC from damage. The CXSD62377 is available in a SOP-8 package.
