Description
The MPM3896-20 is a fully integrated, stackable, synchronous buck module series with a PMBus interface. It offers a complete power solution that integrates a controller, half-bridge FET, and power inductor, offering excellent load and line regulation across a wide 2.8V to 6V input voltage (VIN) range and 0.3V to 0.9 x VIN output voltage (VOUT) range. The MPM3896-20 operates at high efficiency across a wide output current (IOUT) range.
The device provides stackable operation for up to six modules with up to 120A of current capability. It adopts MPS’s proprietary, multi-phase constant-on-time (MCOT) control, which provides ultra-fast transient response and minimizes the required output capacitance. The PMBus interface provides digital configurability and key parameter monitoring.
It also features rich protection functions, including over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), and over-temperature protection (OTP).
The MPM3896-20 requires a minimal number of readily available external components, and is available in a compact ECLGA (5mmx6mm) package.

APPLICATION
OPTICAL MODULESAPPLICATIONOptical modules are optical transceivers used for high-speed data transmission, and are used anywhere larger amounts of data needs to be sent and received. From data centers to telecom, short or long range, optical modules are ideal for large, efficient data transfers. Optical modules can range in size and bandwidth, with the newest generation supporting up to 400GB/s. Due to the large amounts of ...
