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).
