EVQ2183-QH-3001-00A

The EVQ2183-QH-3001-00A is an evaluation board designed to demonstrate the capabilities of the MPQ2183-3001-AEC1, a monolithic, step-down switch-mode converter with built-in internal power MOSFETs. The MPQ2183-3001 achieves up to 3A of output current (IOUT) from a 2.5V to 6V input voltage (VIN) range, with excellent load and line regulation. The output voltage (VOUT) can be regulated to as low as 0.6V. A 100% maximum duty cycle can be reached in low-dropout (LDO) mode. Constant-on-time (COT) control enables a simpler control loop and faster transient response. By using VIN feed forward, the MPQ2183-3001 maintains a nearly constant switching frequency (fSW) across the input and load ranges. Forced continuous conduction mode (FCCM) offers a stable switching frequency (fSW) and a lower output ripple. An open-drain power good (PG) signal indicates a nominal voltage after the soft-start (SS) time (tSS) elapses. If the feedback (FB) voltage (VFB) reaches 95.5% of the reference voltage (VREF), PG is pulled high. When VFB drops to 90% of VREF, PG is pulled low to GND. Full protection features include cycle-by-cycle current limiting, short-circuit protection (SCP), reliable over-voltage protection (OVP), and thermal protection with automatic recovery. The EVQ2183-QH-3001-00A is a fully assembled and tested evaluation board. The MPQ2183-3001 is available in a QFN-8 (1.5mmx2mm) package, and is available in AEC-Q100 Grade 1.
