L6733

Advanced modular synchronous PWM controller

Data Brief

Features

■ High current embedded drivers with

programmable supply voltage

■ Operative supply voltage range: 4.5 V to 16 V

with selectable UVLO threshold

VFQFPN32 5x5 mm

■ Adjustable output voltage: 0.6 V reference

■ 0.8 % accuracy over line ant temperature

Description

variations (0 °C to 125 °C)

■ External reference tracking

L6733 is a single-phase PWM controller designed

to drive N-channel power MOSFETs in a

synhronous rectified buck topology also providing

DCM operations to optimize efficiency in light-

load conditions.

■ Integrated remote sense amplifier

■ Current sharing bus control

■ DCM to optimize efficiency at light-load

■ Hot-plug control capability

The device is specifically designed to implement

redundant and parallelable DC-DC converters.

Current-sharing bus control and OR-Ing fet

driving circuitry are embedded featuring proper

protection management. Synchronization is also

available helping further in reducing input

capacitance in paralleled converters.

■ Margin mode and synchronization

■ Pre-bias start-up management

■ Thermal shut-down

■ Over current protection thermal compensation

■ Programmable over/under voltage protection

■ FB disconnection protection

Programmable margin mode control through

single pin allow saving external logic.

■ Power good output

L6733 provides an integrated 0.6 V reference

allowing regulating output voltages with 0.8 %

accuracy over line and temperature variations

(0 °C to 125 °C) recovering connector and PCB

losses through the remote amplifier provided.

Programmable dual level over current protection

as well as over and under voltage protection are

provided. Current information is monitored across

the main inductor DCR saving the use of

■ Programmable oscillator: 200 kHz to 1 MHz

■ VFQFPN32 package; 5x5 mm

Applications

■ High-performance DC-DC modules

■ Redundant power supply with hot-plug

■ niPoL converters

expensive and space-consuming sense resistors.

Oscillator is internally fixed to 200 kHz and

adjustable up to 1 MHz.
