微源半导体 LP3220S-12B5F SOT23-5 1.5MHz,1.0A降压转换器
General Description
The LP3220S-12B5F is a 1.5MHz constant frequency current mode PWM step-down converter. It is ideal for portable equipment which requires very high current up to 1.0A from single-cell Lithium-ion batteries while still achieving over 94% efficiency during peak load conditions. The LP3220 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 noisy sensitive applications.
The LP3220 can supply up to 1.0A output load current from at VIN = 3V and has an input voltage 2.5V to 5.5V 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 LP3220 is available with adjustable (0.61V to VIN) output voltage. The device is available in a Pb-free, SOT23-5 package and is rated over the temperature range of -40℃ to +85℃.
