1.5MHz, 800mA, High Efficiency PWM
Step-Down DC/DC Converter
General Description
The RT8010B is a high-efficiency Pulse-Width-Modulated
(PWM) step-down DC-DC converter. Capable of delivering
800mA output current over a wide input voltage range from
2.5V to 4V, the RT8010B is ideally suited for portable
electronic devices that are powered from 1-cell Li-ion
battery or from other power sources such as cellular
phones, PDAs and hand-held devices.
Two operating modes are available including PWM/Low-
Dropout autoswitch and shut-down modes. The internal
synchronous rectifier with low R
DS(ON)
dramatically reduces
conduction loss at PWM mode. No external Schottky
diode is required in practical application.
The RT8010B enters Low-Dropout mode when normal
PWM can not provide regulated output voltage by
continuously turning on the upper PMOS. The RT8010B
enters shut-down mode and consumes less than 0.1
μ
A
when EN pin is pulled low.
The switching ripple is easily smoothed-out by small
package filtering elements due to a fixed operating
frequency of 1.5MHz. This along with small WDFN-8L 2x2
package provides small PCB area application. Other
features include soft start, lower internal reference voltage
with 2% accuracy, over temperature protection, and over
current protection.
