Product Description

DESCRIPTION
The TPS5405 is a monolithic non-synchronous buck regulator with wide operating input voltage range from 6.5 V to 28 V. Current mode control with internal slope compensation is implemented to reduce component count. TPS5405 also features a light load pulse skipping mode, which allows for a power loss reduction from the input power supply to the system at light loading. The switching frequency of the converters can be set from 50 kHz to 1.1 MHz with an external resistor. Frequency spread spectrum operation is introduced for EMI reduction.
FEATURES
• Fixed 5-V Output
• 6.5-V to 28-V Wide Input Voltage Range
• Up to 2-A Maximum Continuous Output Loading Current
• Pulse Skipping Mode to Achieve High Light Load Efficiency
• Over 80% Efficiency at 10-mA Loading
• Adjustable 50-kHz to 1.1-MHz Switching Frequency Set by an External Resistor (Leave pin ROSC floating. Set frequency to 120 kHz and ground connection to 70 kHz)
• Peak Current-Mode Control
• Cycle-by-Cycle Over Current Protection
• Switching Node Anti-Ringing to Ease EMI Issue
• External Soft Start
• Available in SOIC8 Package
APPLICATIONS
• 9-V, 12-V and 24-V Distributed Power Systems
• Consumer Applications Such as Home Appliances, Set-Top Boxes, CPE Equipment, LCD Displays, Peripherals, and Battery Chargers
• Industrial and Car Entertainment Power Supplies
