The TPS53124 is a dual synchronous step-down controller designed for low-voltage power rails, operating at a frequency of 380 kHz. It features a wide input voltage range from 4.5 V to 24 V and supports output voltages from 0.76 V to 5.5 V, making it suitable for various applications including digital TVs and networking devices. The controller utilizes D-CAP,Ñ¢ mode, which enables fast transient response and low output ripple, while minimizing external component count and standby consumption. It includes adaptive gate drivers with an integrated boost diode, a built-in 5 V linear regulator, and an internal 1.2 ms voltage-servo soft start. The TPS53124 is available in both 28-pin TSSOP and 24-pin QFN packages, and is specified for operation in ambient temperatures ranging from -40¬8C to 85¬8C.
