Product Description

DESCRIPTION
The TPS54226 is a adaptive on-time D-CAP2™ mode synchronous buck converter. TheTPS54226 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 TPS54226 uses the D-CAP2™ mode control which provides a fast transient response with no external compensation components. The adoptive on-time control supports seamless operation between PWM mode at heavy load condition and reduced frequency Eco-Mode™ operation at light load for high efficiency.
FEATURES
• D-CAP2™ Mode Enables Fast Transient Response
• Low Output Ripple and Allows Ceramic Output Capacitor
• Wide VCC Input Voltage Range: 4.5 V to 18 V
• Wide VIN Input Voltage Range: 2 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
– 160 mΩ (High Side) and 110 mΩ (Low Side)
• High Efficiency, less than 10 μA at shutdown
• Auto-Skip Eco-Mode™ for High Efficiency at Light Load
• High Initial Bandgap Reference Accuracy
• Adjustable Soft Start
• Pre-Biased Soft Start
• 700-kHz Switching Frequency (fSW)
• Cycle By Cycle Over Current Limit
• Power Good Output
• Auto-Skip Mode
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)
