P2680 Datasheet

WIDE INPUT 2A STEP DOWN  CONVERTER  
 
 
 
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.
