RT6373B - Buck Converter

This page provides the datasheet information for the RT6373B, a member of the RT6373A Buck Converter family.

Description

The RT6373A/B is a simple, easy-to-use, 3A synchronous step-down DC-DC converter with an input supply voltage range of 4.5V to 17V.

The device possesses an accurate reference voltage and integrates low RDS(ON) power MOSFETs to achieve high efficiency.

Features

cycle-by-cycle current limit protection to prevent the device from the catastrophic damage in output short circuit, over-current or inductor saturation conditions. A built-in soft-start function prevents inrush current during start-up. The device also includes input under-voltage Features.
3A Converter Integrated 95m and 50m FETs.
Input Supply Voltage Range : 4.5V to 17V.
Output Voltage Range : 0.6V to 7V.
Advanced Constant On-Time (ACOT® ) Control.
Ultrafast Transien.

RT6373A/B 17V Input, 3A, ACOT® Buck Converter with Both FETs OC Protection General Description The RT6373A/B is a simple, easy-to-use, 3A synchronous step-down DC-DC converter with an input supply voltage range of 4.5V to 17V. The device possesses an accurate reference voltage and integrates low RDS(ON) power MOSFETs to achieve high efficiency. The RT6373A/B adopts Advanced Constant On-Time (ACOT® ) control architecture to provide an ultrafast transient response with few external components and to operate in nearly constant switching frequency over the line, load, and output voltage range. The RT6373A operates in automatic PSM that maintains high efficiency during light load operation. The RT6373B operates in Forced PWM that helps meet tight voltage regulation accuracy requirements.
