1 / 17 page  RT8011/A 1 DS8011/A-00 August 2006 www.richtek.com Features High Efficiency : Up to 95% Low RDS(ON) Internal Switches : 110m Ω Ω Ω Ω Ω Programmable Frequency : 300kHz to 4MHz No Schottky Diode Required 0.8V Reference Allows Low Output Voltage Forced Continuous Mode Operation Low Dropout Operation : 100% Duty Cycle Synchronizable Switching Frequency (For RT8011 Only) Power Good Output Voltage Monitor (For RT8011 Only) RoHS Compliant and 100% Lead (Pb)-Free Applications Portable Instruments Battery-Powered Equipment Notebook Computers Distributed Power Systems IP Phones Digital Cameras General Description The RT8011/A 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. The internal synchronous low on-resistance power switches increase efficiency and eliminate the need for an external Schottky diode. Switching frequency is set by an external resistor or can be synchronized to an external clock. 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. RT8011/A operation in forced continuous PWM Mode which minimizes ripple voltage and reduces the noise and RF interference. 100% duty cycle in Low Dropout Operation further maximize battery life. Note : RichTek Pb-free and Green products are : RoHS compliant and compatible with the current require- ments of IPC/JEDEC J-STD-020. Suitable for use in SnPb or Pb-free soldering processes. 100% matte tin (Sn) plating.
