TPS62303YZDT TI Step-Down Converter | 8-DSBGA | 3MHz, 500mA

Product Overview

The TPS62303YZDT from Texas Instruments is a high-frequency, synchronous step-down DC-DC converter optimized for battery-powered portable applications. Housed in a compact 8-DSBGA package, it delivers up to 500mA output current with excellent efficiency. The device operates at a fixed 3MHz switching frequency, enabling the use of small external components while maintaining low output ripple.

Detailed Technical Specifications

Key Features

• High efficiency up to 95% extends battery life
• 3MHz fixed frequency allows small inductor and capacitor values
• Low quiescent current of 35µA for light-load efficiency
• Power-save mode for improved efficiency at low output currents
• Internal soft-start reduces inrush current
• Over-temperature and over-current protection
