Introduction
The TX4138 is a monolithic step-down switch mode converter. It achieves 4A continuous output current over a wide input supply range with excellent load and line regulation. The maximum peak current can be programmed by sensing current through an accurate sense resistor. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. The TX4138 requires a minimum number of readily available standard external components. The TX4138 is available in 8-pin ESOIC8 packages.
Features
- Wide 4.5V to 60V Operating Input Range
- Output Adjustable from 0.8V to 40V
- Standby Current 400uA
- Power Save Mode at light load
- Programmable maximum peak current
- 32mΩ Internal Power MOSFET Switch
- 93% Efficiency at Vin = 60V，Vout = 12V@2A
- 84.5% Efficiency at Vin = 60V，Vout = 5V@2A
- Fixed 200KHz Frequency
- Thermal Shutdown
- Cycle-by-Cycle Over Current Protection
- Available in 8-Pin ESOIC8 Packages
Applications
- Balance Bike
- Ebike
- USB Power Supplies
