EP3003 2-CH, 600mA Synchronous Step-down Converter DESCRIPTION The EP3003 is a dual channel, 1.5MHz constant frequency, slope compensated current mode PWM step-down converter. The EP3003 can supply 600mA of load current from a 2.5V to 5.5V input voltage. Each output voltage is adjustable from 0.6V to 5V. It is ideal for powering portable equipment that runs from a single cell lithium-Ion (Li+) battery. Internal synchronous 0.35, 1A power switches provide high efficiency without the need for external Schottky diodes. The EP3003 can also run at 100% duty cycle for low dropout operation, extending battery life in portable system. Pulse Skipping Mode operation at light loads provides very low output ripple voltage for noise sensitive applications. Burst Mode operation provides higher efficiency at light loads. FEATURES High Efficiency: Up to 96% 1.5MHz Constant Switching Frequency 600mA Output Current Integrated Main Switch and Synchronous Rectifier High Switch Current: 1A on Each Channel 2.5V to 5.5V Input Voltage Range Output Voltage as Low as 0.6V 100% Duty Cycle in Dropout Low Quiescent Current: 50μA Slope Compensated Current Mode Control for Excellent Line and Load Transient Response Can be synchronized to an external oscillator Short Circuit Protection Power-on Reset Output Thermal Fault Protection <1uA Shutdown Current Small Thermally Enhanced 10-Pin MSOP and 3mm × 3mm DFN Packages APPLICATIONS Cellular and Smart Phones Microprocessors and DSP Core Supp……
