Product Description

The TPS54528DDA is an adaptive on-time D-CAP2™ mode synchronous Buck Converter for use with digital set-top box (STB). The TPS54528 enables system designers to complete the suite of various end-equipment power bus regulators with low component count and low standby current solution. The main control loop for the TPS54528 uses the D-CAP2™ mode control that provides a fast transient response with no external compensation components. The adaptive on-time control supports seamless transition between PWM mode at higher load conditions and Eco-mode™ operation at light loads. Eco-mode™ allows the TPS54528 to maintain high efficiency during lighter load conditions. The TPS54528 also has a proprietary circuit that enables the device to adopt to both low equivalent series resistance (ESR) output capacitors, such as POSCAP or SP-CAP and ultra-low ESR ceramic capacitors. The device operates from 4.5 to 18V VIN input. The output voltage can be programmed between 0.76 and 6V.
D-CAP2™ mode enables fast transient response
Low output ripple and allows ceramic output capacitor
Highly efficient integrated FETs optimized for lower duty cycle applications
High efficiency, less than 10µA at shutdown
High initial bandgap reference accuracy
Adjustable soft-start
Prebiased soft-start
Cycle-by-cycle overcurrent limit
Auto-skip Eco-mode™ for high efficiency at light load
Green product and no Sb/Br
