UD05251 Description
The UTC UD05251 is a 1.2MHz constant frequency current mode PWM step-down converter. It is ideal for portable equipment requiring very high current up to 2.5A from single-cell Lithium-ion batteries while still achieving over 90% efficiency during peak load conditions. The UTC UD05251 also can run at 100% duty cycle for low dropout operation, extending battery life in portable systems while light load operation...
