TD1742 Overview
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.
Key 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
- 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
