General Description

TD1742‐2COT is a DC/DC Buck Controller with 2 current sense

pins suitable for many multi‐output applications. It is

designed to allow for operating a wide supply voltage range

from 7.5V to 40V. It has both high‐side and low‐side drivers

allowing synchronous configuration using two external

power‐NMOS. It can operate in both Constant Current (CC)

and Constant Voltage (CV) modes.

TD1742‐2COT operates as a DC/DC Buck Controller providing

a wide range of outputs at Constant Voltage (CV) from 1.20V

to 28V and the output current as high as 10A or above. It has

a Constant Current(CC) mode so that output current can be

set externally and at a accuracy of +/‐7%.

The current mode control that makes feedback control have

good line and load regulation with flexible external design.

There are 2 independent current limit control pins in addition

to the CC setting for added flexibility of driving 2 separate

loads. Each of the current limits can be set by a sense resistor

at 100mV across it. At the same time, output peak current

limit is working during normal operation.

Features

? Vin: 7.5V to 40V

? Vout: 3V to 28V; typical at 5V

? CC/CV Mode Control

? Burst/PFM Mode for Increased Light Load

Efficiency

? Hiccup mode 1‐2S when SCP/OVP occur

? Protection

NMOS peak current limit: accuracy:~20%

Output short protection: reduce input current to

less than 20mA(RMS)

OVP(output Over‐Voltage Protection)

Output FB short protection

Temperature shut down(OTP).

? Adjustable Output Cable Resistance Compensation

? Duty: 0~98%(Toff_min=100ns, Deadtime=25~35ns)

? Switching Frequency: 150KHz(+/‐25k)

? Integrated MOSFET Driver.

? OVP: When Vfb>140%*VREF, open discharge

switch ( Vout1/2). Discharge current> 50mA

? QFN‐16 Package

Applications

? Car Charger

? High‐Brightness Lighting

? General‐Purpose DC/DC Controller
