MP8886GUT

MPL Optimized Performance with MPS Inductor The MP8886 is a 45V input, dual-phase, dual-output, high-efficiency, synchronous step-down converter with a PMBus control interface and multiple-time programmable (MTP) memory. The device can achieve up to 3A of continuous output current (IOUT) for two channels, or up to 6A of continuous IOUT for a single channel, with excellent load and line regulation across a wide input voltage (VIN) 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. The voltage transition rate, switching frequency (fSW), and power-saving modes can also be configured via the PMBus interface. Peak current mode control provides fast transient response and eases loop stabilization. Full protection features include VIN under-voltage lockout (UVLO) protection, over-voltage protection (OVP), over-current protection (OCP), and thermal shutdown. The MP8886’s MTP memory provides flexible configuration options. The device can be paralleled with up to four phases, and it has an automatic phase-shift function 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. With internal compensation and a feedback divider, the MP8886 offers a very compact solution with a minimal number of readily available, standard external components. The MP8886 is available in a TQFN-26 (5mmx5mm) package.
