RT6263A規(guī)格書(shū)詳情

General Description

The RT6263A/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 RT6263A/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 RT6263A

operates in automatic PSM that maintains high

efficiency during light load operation. The RT6263B

operates in Forced PWM that helps meet tight voltage

regulation accuracy requirements.

The RT6263A/B senses both FETs current for a robust

over-current protection (OCP). The device 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.

The RT6263A/B offers programmable start-up by

connecting a capacitor at external SS pin. The device

also includes input under-voltage lockout, output

under-voltage protection, and over-temperature

protection (OTP) to provide safe and smooth operation

in all operating conditions.
