The TPS53124 is a dual, Adaptive on-time DCAP mode synchronous controller. The part enables system designers to cost effectively complete the suite of digital TV power bus regulators with the absolute lowest external component count and lowest standby consumption. The main control loop for the TPS53124 uses the D-CAP™ mode that optimized for low ESR output capacitors such as POSCAP or SP-CAP promises fast transient response with no external compensation. The part provides a convenient and efficient operation with conversion voltages from 4.5 V to 24 V and output voltage from 0.76 V to 5.5 V.
