Techcode TD1489
TD1489 is a Synchronous Buck Circuit with two current sense pins suitable for many multi-output applications. It is designed to allow for operating a wide supply voltage range from 4.7V to 40V.This IC can operate in both Constant Current (CC) and Constant Voltage (CV) modes. It has a Constant Current (CC) mode so that output current can be set externally and at an accuracy of ±4%.| Part No. | TD1489 |

GENERAL DESCRIPTION
FEATURES
TD1489 operates as a Buck Circuit providing a wide range of outputs at Constant Voltage (CV) from 4.7V to 40V and the output current as high as 6A or above. The current mode control and external compensation makes feedback control have good line and load regulation with flexible external design. Pin Configurations● Vin: 4.7V to 40V
● Vout: 1.2V to Vin*97%V; 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
● Switching Frequency: 125k+25k
● Integrated Power MOSFET
● QFN32L Package
