1 / 14 page  RT8015D 1 DS8015D-02 March 2011 www.richtek.com Features High Efficiency : Up to 95% Low RDS(ON) Internal Switches : 110m Ω Ω Ω Ω Ω Programmable Frequency : 300kHz to 2MHz No Schottky Diode Required 0.8V Reference Allows for Low Output Voltage Forced Continuous Mode Operation Low Dropout Operation : 100% Duty Cycle Power Good Output Voltage Indicator RoHS Compliant and Halogen Free Applications Portable Instruments Battery-Powered Equipment Notebook Computers Distributed Power Systems IP Phones Digital Cameras General Description The RT8015D 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 3A of output current. 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. The 100% duty cycle provides low dropout operation extending battery life in portable systems. Current mode operation with external compensation allows the transient response to be optimized over a wide range of loads and output capacitors. The RT8015D is operated in forced continuous PWM Mode which minimizes ripple voltage and reduces the noise and RF interference. The 100% duty cycle in Low Dropout Operation further maximize battery life. The RT8015D is available in the WDFN-10L 3x3 package.
