JM2420 - JABRIEL

JM2420 2A Synchronous Step-Down Converter

The JM2420 is a 1.4MHz constant frequency current mode PWM step-down converter. It Typical Application 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 JM2420 also can run at 100% duty cycle for low dropout operation, extendi.
