Techcode TD1741
TD1741 is a Synchronous Buck Controller with two current sense pins suitable for many multi-output applications. It is designed to allow for operating a wide supply voltage range from 6V to 40V. It has both high-side and low-side drivers allowing synchronous configuration using two external power-NMOS。This IC can operate in both Constant Current (CC) and Constant Voltage (CV) modes.| Part No. | TD1741 |

GENERAL DESCRIPTION
FEATURES
TD1741 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. Pin Configurations● Vin: 6V to 40V, UVLO=5.5V+0.5V
● Vout: 1.2V to Vin*98%; 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...
