® RT8077 2A, 2MHz, Synchronous Step-Down Converter General Description Features The RT8077 is a high efficiency synchronous, step-down DC/DC converter. Its input voltage range is from 2.6V to 5.5V and provides an adjustable regulated output voltage from 0.8V to 5V, while delivering up to 2A of output current. z The internal synchronous low on-resistance power switches increase efficiency and eliminate the need for an external Schottky diode. The switching frequency is set by an external resistor or can be synchronized to an external clock. The 100% duty cycle provides low dropout operation extending battery life in portable systems. z z z z z z z z z z Current mode operation with external compensation allows the transient response to be optimized over a wide range of loads and output capacitors. High Efficiency : Up to 95% Low RDS(ON) Internal Switches : 90mΩ Ω Programmable Frequency : 300kHz to 2MHz No Schottky Diode Required 0.8V Reference Allows for Low Output Voltage Low Dropout Operation : 100% Duty Cycle 2.6V to 5.5V Input Voltage Range VOUT Range from 0.8V to 5V Up to 2A Output Current Thermal Shutdown RoHS Compliant and Halogen Free Applications z The 100% duty cycle in Low Dropout Operation further maximize battery life. z The RT8077 is available in the WDFN-8L 2x2 package. z z z z z Portable Instruments Battery-Powered Equipment Notebook Computers Distributed Power Systems IP Phones Digital Cameras Dynamic Supply Bias for GSM/EDGE PAs and 3G/4G PAs Simplified Application Circuit VIN CIN ROSC PVDD COMP RT8077 FB RCOMP R2 CF RT PGND CCOMP R1 L1 LX GND Copyright © 2013 Richtek Technology Corporation.
