Description
- DESCRIPTION
- The TPS5402 is a monolithic non-synchronous buck regulator with wide operating input voltage range from 3.5 V to 28 V. Current mode control with internal slope compensation is implemented to reduce component count. TPS5402 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.
- A cycle-by-cycle current limit with frequency fold back protects the IC at over loading condition.
- FEATURES
- • 3.5-V to 28-V Wide Input Voltage Range
- • Up to 1.7-A Maximum Continuous Output Loading Current
- • Pulse Skipping Mode to Achieve High Light Load Efficiency
- • High Light Load Efficiency
- • Frequency Spread Spectrum to Reduce EMI
- • 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)
- • Frequency Spread Spectrum to Ease EMI Issue
- • Peak Current-Mode Control
- • Cycle-by-Cycle Over Current Protection
- • External Soft Start
- • Available in SOIC8 Package
- APPLICATIONS
- • 5-V, 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
