The TPS566242 is a 3V to 16V input voltage, 6A ECO mode, synchronous buck converter in a SOT-563 package

The TPS566242 is a simple, easy-to-use, high power density, high efficiency AAT2845IML-EE-T1 synchronous buck converter with an input voltage range of 3V to 16V and supports up to 6A continuous current in a SOT563 package.

The TPS566242 uses a DCAP3 topology to provide fast transient response and support low ESR output capacitors without external compensation. It has two grounds, GND and AGND, which should be connected together for best thermal performance. AGND also provides good load and line regulation. It can support up to 95% load operation.

The TPS566242 operates in Eco mode to maintain high efficiency during light loads. The TPS566247 operates in FCCM mode to maintain the same frequency and lower output ripple under all load conditions. It integrates complete protection via OVP, OCP, UVLO, OTP and UVP with hiccup. The device is housed in a 1.6mm × 1.6mm SOT563 package with an optimized pinout for easy PCB layout. Junction temperature is specified from –40°C to 125°C.
