AAT1145 Datasheet | Advanced Analogic Technologies

PRODUCT DATASHEET SwitchRegTM General Description The AAT1145 SwitchReg™ is a 1.5MHz constant frequency current mode PWM step-down converter. It is ideal for portable equipment requiring very high current up to 1.2A from single-cell Lithium-ion batteries while still achieving over 90% efficiency during peak load conditions. The AAT1145 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 AAT1145 can supply up to 1.2A output load current from a 2.5V to 5.5V input voltage and the output voltage can be regulated as low...
