Product Description

DESCRIPTION
The TPS54426 is an adaptive on-time D-CAP2™ mode synchronous buck converter. The TPS54426 enables system designers to complete the suite of various end equipment’s power bus regulators with a cost effective, low component count, low standby current solution. The main control loop for the TPS54426 uses the D-CAP2™ mode control which provides a very fast transient response with no external compensation components.
FEATURES
• D-CAP2™ Mode Enables Fast Transient Response
• Low Output Ripple and Allows Ceramic Output Capacitor
• Wide VIN Input Voltage Range: 4.5 V to 18 V
• Output Voltage Range: 0.76 V to 5.5 V
• Highly Efficient Integrated FET’ s Optimized for Lower Duty Cycle Applications
– 65 mΩ (High Side) and 55 mΩ (Low Side)
• High Efficiency, less than 10 μA at shutdown
• High Initial Bandgap Reference Accuracy
• Adjustable Soft Start
• Pre-Biased Soft Start
• 700-kHz Switching Frequency (fSW)
• Cycle By Cycle Over Current Limit
