RT5710B - CMCOT Synchronous Step-Down Converter

Description

The RT5710B is a simple, easy-to-use, 1A synchronous step-down DC-DC converter with an input supply voltage range of 2.5V to 6V.

The device build-in an accurate 0.6V reference voltage and integrates low RDS(ON) power MOSFETs to achieve high efficiency in a WDFN-6L 2x2 package.

Features

  • cycle-by-cycle current limit protection and prevent the device from the catastrophic damage in output short circuit, over current or inductor saturation. An Internally soft-start function prevents inrush current during start-up. The device also includes input under-voltage lockout, output under-voltage protection, and over-temperature protection (thermal shutdown) to provide safe and smooth operation in all operating conditions. The RT5710B is offered in a WDFN-6L 2x2 package. Features.

RT5710B 6V, 1A, 1.5MHz, CMCOT Synchronous Step-Down Converter General Description The RT5710B is a simple, easy-to-use, 1A synchronous step-down DC-DC converter with an input supply voltage range of 2.5V to 6V. The device build-in an accurate 0.6V reference voltage and integrates low RDS(ON) power MOSFETs to achieve high efficiency in a WDFN-6L 2x2 package. The RT5710B adopts Current Mode Constant On-Time (CMCOT) 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 RT5710B operates in Forced PWM that helps meet tight voltage regulation accuracy requirements. The RT5710B senses Low-Side FETs current for a robust over-current protection.
