The TPS54425PWP is an adaptive on-time D-CAP2™ mode synchronous Buck Converter for use with digital TV power supply. The TPS54425 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 TPS54425 uses the D-CAP2™ mode control which provides a very fast transient response with no external compensation components. The TPS54425 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 0.76V and 5.5V. The device also features an adjustable soft-start time and a power good function.
● D-CAP2™ mode enables fast transient response
● Low output ripple and allows ceramic output capacitor
● Highly efficient integrated FET"s optimized for lower duty cycle applications
● High initial bandgap reference accuracy
● Adjustable soft-start
● pre-biased soft-start
● Cycle-by-cycle over current limit
● Power good output
● High efficiency, less than 10µA at shutdown
● Green product and no Sb/Br
