概述

The LP3202 is a 1.5MHz constant frequency current mode PWM step-down converter. integrates main switch and synchronous rectifier switch. The LP3202 integrates two operation modes, PWM control and PFM mode switching control, which allows a high efficiency over the wider range of the load. It is ideal for portable equipment which requires very high current up to 2.0A from single-cell Lithium-ion batteries while still achieving over 96% efficiency during peak load conditions. The LP3202 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 LP3202 can supply up to 2.0A output load current from at VIN = 3V and has an input voltage 2.5V to 6V and the output voltage can be regulated as low as 0.61V. 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 device is available in a Pb-free SOT23-5 package and is rated over the temperature range of -40°C to +85°C.
