RT5788A/B

6V, 4A, 1.5MHz ACOT^TMSynchronous Step-Down Converter

in TSOT-23-8 package

General Description

Features

^4A Converter With Built-In 22mΩ/20mΩ Low

R_DS(ON)Power FETs

The RT5788A/B is a simple, easy-to-use, 4Asynchronous

step-downDC-DC converter with an input supply voltage

range of 2.5V to 6V. The device build-in an accurate 0.6V

( 1.5%) reference voltage and can operate in 100% duty

cycle as a very low dropout voltage regulator. The

RT5788A/B integrates low R_DS(ON)power MOSFETs to

achieve high efficiency and is available in TSOT-23-8 (FC)

package.

^Input Supply Voltage Range : 2.5V to 6V

^Output Voltage Range : 0.6V to 6V

^Operates Up to 100% Duty Cycle

^Advanced Constant On-Time (ACOT^TM) Control

^Ultrafast Transient Response

^No Needs for External Compensations

^Optimized for Low-ESR Ceramic Output Capacitors

^0.6V 1.5% High-Accuracy Feedback Reference

Voltage

The RT5788A/B adopts Advanced Constant On-Time

(ACOT^TM) 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 RT5788A/B is

designed to operate at 1.5MHz fixed frequency. While

the RT5788A automatically enters power saving mode

(PSM) operation at light load to maintain high efficiency.

The RT5788B operates in Forced PWM over the loading

range, that helps meet tight voltage regulation accuracy

requirements.

 35μA Operation Quiescent Current (RT5788A)

 Robust Over-Current Protection for Both FETs

 Optional for Operation Modes :

 Power Saving Mode (PSM) (RT5788A)

 Forced PWM Mode (RT5788B)

 Fixed Switching Frequency : 1.5MHz

 Monotonic Start-Up for Pre-Biased Output

 Individual Enable Control Input

 Power Good Indicator

The RT5788A/B senses both FETs current for a robust

over-current protection. It prevents the device from the

catastrophic damage in output short circuit, over current

or inductor saturation. The individual enable control input

and power good indicator provides flexible system power

sequence control a built-in 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.

 Built-In Internally Fixed Soft-Start (Typ. 1.5ms)

 100% Duty Cycle Mode

 Internal Output Discharge

 Input Under-Voltage Lockout (UVLO)

 Output Under-Voltage Protection (UVP) with Hiccup

Mode

 Over-Temperature Protection

 Available in TSOT-23-8 (FC) Package
