The TPS5130 consists of three independent synchronous buck regulator controllers (SBRCs) and one low-dropout (LDO) regulator controller. On-chip high-side and low-side synchronous rectification drivers are integrated into the driver's cheaper N-channel MOSFETs. The LDO controller can also drive an external N-channel MOSFET. Due to the input current ripple, a phase minimization of 180 degrees is operated, which allows for smaller input capacitance to reduce power costs. The TPS5130 SBRC automatically adjusts skip mode from PWM mode to maintain high efficiency at light loads. A resistor-less synchronous buck controller and fixed high-side drive voltage protection simplify system design and reduce external component count.
