Texas Instruments TPS566247

Description

The TPS56624x is simple, easy-to-use, high power density, high efficiency synchronous buck converter with input voltage ranging from 3 V to 16 V andsupports up to 6-A continuous current with a SOT563 package.The TPS56624x uses DCAP3 topology to provide a fast transient response and to support low-ESR output capacitors with no requirement for external compensation. It has two grounds, GND and AGND,which should be connected together for optimal thermal performance. AGND also provides a good load and line regulation. It can support up to 95% duty operation.The TPS566242 operates in Eco-mode, which maintains high efficiency during light loading. The TPS566247 operates in FCCM mode, which keeps the same frequency and lower output ripple during all load conditions. It integrates complete protectionthrough OVP, OCP, UVLO, OTP, and UVP with hiccup. The device is available in 1.6-mm × 1.6-mm SOT563 package and has an optimized pinout for easy PCB layout. The junction temperature is specified from –40°C to 125°C.
