RT8015

2A, 2MHz, Synchronous Step-Down Regulator

General Description

Features

l High Efficiency : Up to 95%

The RT8015 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.

l Low R_DS(ON)Internal Switches : 110mW

l Programmable Frequency : 300kHz to 2MHz

l No Schottky Diode Required

l 0.8V Reference Allows Low Output Voltage

l Forced Continuous Mode Operation

l Low Dropout Operation : 100% Duty Cycle

l RoHS Compliant and 100% Lead (Pb)-Free

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.

Applications

l Portable Instruments

l Battery-Powered Equipment

l Notebook Computers

l Distributed Power Systems

l IP Phones

RT8015 operation in forced continuous PWM Mode which

minimizes ripple voltage and reduces the noise and RF

interference. 100% duty cycle in LowDropout Operation

further maximize battery life.
