The TPS5130 is composed of three independent synchronous buck regulator controllers (SBRC) and one low dropout (LDO) regulator controller. On-chip high-side and low-side synchronous rectifier drivers are integrated to drive less expensive N-channel MOSFETs. The LDO controller can also drive an external N-channel MOSFET. Because the input current ripple is minimized by operating 180° out of phase, it allows a smaller input capacitance, resulting in reduced power supply cost. The SBRC of the TPS5130 automatically adjusts from PWM mode to SKIP mode to maintain high efficiency under light-load conditions. Resistorless current protection for the synchronous buck controller and the fixed high-side driver voltage simplifies the system design and reduces the external parts count. The LDO controller has a current-limit protection and overshoot protection to suppress output voltage spikes at load transient. To further extend battery life, the TPS5130 features dead-time control and very low quiescent current.
