ET8020 - 1.2MHz constant frequency current mode PWM step-down converter

Description

The ET8020 is a 1.2MHz constant frequency current mode PWM step­down converter.

It is ideal for applications requiring very high current up to 2A while still achieving over 90% efficiency during peak load conditions.

Features

  • Input Voltage Range: 2.5V to 5.5V Output Voltages from 0.6V to VIN 2A Output Current High Efficiency: Up to 95% 1.2MHz Constant Switching Frequency Allows Use of Ceramic Capacitors Current Mode Operation for Excellent Line and Load Transient Response Short­Circuit and Thermal Fault Protection Soft Start Low Dropout Operation: 100% Duty Cycle ­40°C to +85°C Temperature Package：ET8020Y(DFN­10), ET8020M(SOP8)，ET8020(SOT23­5), ET8020YD(DFN­6)   .

General Description The ET8020 is a 1.2MHz constant frequency current mode PWM step­down converter. It is ideal for applications requiring very high current up to 2A while still achieving over 90% efficiency during peak load conditions. The ET8020 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 ET8020 can supply up to 2A output load current from a 2.5V 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.
