Product Description

The TPS54427DDA is an adaptive on-time D-CAP2™ mode synchronous Buck Converter for use with digital set-top box (STB). The TPS54427 enables system designers to complete the suite of various end equipment"s power bus regulators with low component count and low standby current solution. The main control loop for the TPS54427 uses the D-CAP2™ mode control which provides a fast transient response with no external compensation components. The TPS54427 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 7V. The device also features an adjustable soft-start time.
D-CAP2™ mode enables fast transient response

Highly efficient integrated FETs optimized for lower duty cycle applications
High initial bandgap reference accuracy
Adjustable soft-start
pre-biased soft-start
Cycle-by-cycle overcurrent limit
High efficiency, less than 10µA at shutdown
Green product and no Sb/Br
