General Description

EC1741 is a Synchronous Buck Controller with two current sense pins suitable for many multi­output applications.

It is designed to allow for operating a wide supply voltage range from 6V to 40V.

It has both high­side and low­side drivers allowing synchronous configuration using two external power­NMOS。

This IC can operate in both Constant Current (CC) and Constant Voltage (CV) modes. EC1741 operates as a Buck Controller providing a wide range of outputs at Constant Voltage (CV) from 6V to 40V 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 an accuracy of ±4%.

The current mode control and external compensation makes feedback control have good line and load regulation with flexible external design.

Features

◆Vin: 6V to 40V, UVLO=5.5V+0.5V
◆Vout: 3V to 28V; typical at 5V
◆Precision CC/CV Mode Control
◆Burst/PFM Mode for Increased Light Load Efficiency
◆2 outputs independent Constant Current setting
◆Hiccup mode when output voltage below 50% normal output voltage
◆Protection:
NMOS peak current limit: accuracy:~20%
Output short protection: reduce input current to less than 20mA (RMS)
Output FB OVP (125% VFB), only turn off High side MOS.
Temperature shutdown (OTP)
◆ Adjustable Output Cable Resistance Compensation
◆ Duty: 0~98% (Toff_min=100ns, Dead­time=25~35ns)
◆Switching Frequency: 125k+25k
◆Integrated MOSFET Drivers
◆QFN12L Package

Applications

◆Car Charger
◆High­Brightness Lighting
◆General­Purpose DC/DC Application
