RT8055ZQW Dettagli del prodotto

General Description

The RT8055 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.



Features

High Efficiency : Up to 95%

Low RDS(ON) Internal Switches : 100mΩ

Programmable Frequency : 300kHz to 2MHz

No Schottky Diode Required

0.8V Reference Voltage Allows for Low Output Voltage
