STEP-DOWN CONVERTER



DESCRIPTION

The UTC UD05201 is a 1.2MHz constant frequency current mode

PWM step-down converter. It is ideal for portable equipment

requiring very high current up to 2A from single-cell Lithium-ion

batteries while still achieving over 90% efficiency during peak load

conditions. The UTC UD05201 also can run at 100% duty cycle for

low dropout operation, extending battery life in portable systems

while light load operation provides very low output ripple for noise

sensitive applications. The UTC UD05201 can supply up to 2A

output load current from a 2.6V to 5.5V input voltage and the output

voltage can be regulated as low as 0.6V. The high switching

frequency minimizes the size of external components while keeping

switching losses low. The internal slope compensation setting allows

the device to operate with smaller inductor values to optimize size

and provide efficient operation. The UTC UD05201 is available in

adjustable (0.6V to V_IN) output voltage.
