1 / 22 page U1 TPS54429PWP Vout (50 mV/div) Iout (2A/div) 100 s/div m TPS54429 www.ti.com SLVSAS1 – FEBRUARY 2011 7V to 18V Input, 4.5-A Synchronous Step-Down ( SWIFT ™) Converter Check for Samples: TPS54429 1 FEATURES DESCRIPTION 23 • D-CAP2 ™ Mode Enables Fast Transient Response The TPS54429 is an adaptive on-time D-CAP2 ™ mode synchronous buck converter. The TPS54429 • Low Output Ripple and Allows Ceramic Output enables system designers to complete the suite of Capacitor various end equipment ’s power bus regulators with a • Wide VIN Input Voltage Range: 7 V to 18 V cost effective, low component count, low standby • Output Voltage Range: 0.76 V to 5.5 V current solution. The main control loop for the TPS54429 uses the D-CAP2 ™ mode control which • Highly Efficient Integrated FET ’s Optimized provides a very fast transient response with no for Lower Duty Cycle Applications external compensation components. The TPS54429 – 63 mΩ (High Side) and 55 mΩ (Low Side) also has a proprietary circuit that enables the device • High Efficiency, less than 10 μA at shutdown to adopt to both low equivalent series resistance • High Initial Bandgap Reference Accuracy (ESR) output capacitors, such as POSCAP or SP-CAP, and ultra-low ESR ceramic capacitors. The • Adjustable Soft Start device operates from 7-V to 18-V VIN input. The • Pre-Biased Soft Start output voltage can be programmed between 0.76 V • 700-kHz Switching Frequency (fSW) and 5.5 V. The device also features an adjustable soft start time and a power good function. The • Cycle By Cycle Over Current Limit TPS54429 is available in the 14-pin HTSSOP • Power Good Output package, and designed to operate from –20°C to 85 °C. APPLICATIONS • Wide Range of Applications for Low Voltage System – Digital TV Power Supply – High Definition Blu-ray Disc™ Players – Networking Home Terminal – Digital Set Top Box (STB) 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 SWIFT, D-CAP2, PowerPAD are trademarks of Texas Instruments. 3 Blu-ray Disc is a trademark of Blu-ray Disc Association.
