4.5-V to 18-V Input, 2-A Synchronous Step-Down SWIFT™ Converter: With
D-CAP2™ architecture, the TPS54227 provides better than 20-µs transient response time, ¼ of the time of typical current mode or voltage mode control using similar 22-µF ceramic output capacitors. As a result, output voltage ripple of less than 10mV is achievable without compensation components and tedious loop-response calculations.
Resources: Data sheet, evaluation module, PSpice transient model

• Integrated 155-mΩ high-side and 108-mΩ low-side MOSFETs
• Adjustable soft-start time
• Applications: Digital TV, HD Blu-Ray, networking home terminal, set-top box

TPS54227: Price (1ku): $1.45 - $1.75
