MP8880AGVE

MPL Optimized Performance with MPS Inductor The MP8880A is a high-frequency, synchronous, rectified step-down converter with a PMBus control interface. It can achieve up to 4.5A of continuous output current (IOUT), with excellent load and line regulation across the wide input voltage (VIN) supply range. The output voltage (VOUT) can be controlled on the fly via the PMBus serial interface. VOUT can be set between 0.6V and 24V in internal feedback divider mode, with a 48V maximum in external feedback divider mode. The voltage slew rate, switching frequency (fSW), and power-save mode can also be selected via the PMBus interface. Current mode operation provides fast transient response and eases loop stabilization. Full protection features include under-voltage lockout (UVLO), over-voltage protection (OVP), over-current protection (OCP), and thermal shutdown. The MP8880A supports multiple-time programmable (MTP) memory to provide flexible configurations. The device can be paralleled with up to 4 phases for applications with a higher IOUT. The integrated, internal high-side and low-side power MOSFETs (HS-FETs and LS-FETs, respectively) provide high efficiency without the use of an external Schottky diode. The internal feedback divider and compensation make the MP8880A a very compact solution with a minimal number of readily available, standard external components. It is available in a QFN-20 (4mmx5mm) package.
