P2680中文资料WIDE INPUT 2A STEP DOWN  CONVERTER数据手册UTC规格书

描述 Description

The UTC P2680 is a step-down, fixed 420kHz frequency,current-mode, PWM controller with an internal power MOSFET. It achieves 2A continuous output current over a wide input supply range from 4V to 26V with excellent load and line regulation. Equipped with an external compensation pin, this device offers user flexibility in determining loop dynamic. Current mode control provides fast transient response and cycle-by-cycle current limit. A PWM control circuit can provide the duty ratio from 0 up to 90% linearly. An Under-Voltage-Lock-Output (UVLO) circuit monitors the VIN supply voltage to prevent wrong logic controls. Additional under voltage protections monitor the voltage on FB pin for short-circuit protections. In application, the UTC P2680 is suitable for portable devices when it works as an ideal power supply in SOP-8L package.
