TPS5124 双通道同步降压 PWM 控制器 30-TSSOP -40 to 85
The TPS5124 is dual independent high efficiency synchronous step-down controller. It supports a low-voltage/high-current power supply applications that use either a 5-V or 12-V bus voltage. Since both controllers of the TPS5124 operate 180 degree out-of-phase, the input current ripple is minimized resulting in a smaller input capacitance and reduced power supply cost.
The current protection circuit detects the drain-to-source voltage drop across the high-side and low-side power MOSFET while it is conducting. Also, the current protection circuit has a temperature coefficient to compensate for the RDSon variation of the MOSFET. This resistor-less current protection and built-in boost diode simplify the system design and reduces the external parts count. Other features such as undervoltage lockout, overvoltage, undervoltage, and programmable short-circuit protection promote system reliability.
