Description
The EVM81204-BC-00A is designed to demonstrate the capabilities of the MPM81204, a quad-output step-down module with dual 12A and dual 5A outputs. It operates at a high efficiency across a wide output current load range. The operation frequency is configurable to 600kHz, 800kHz, or 1000kHz with a single resistor, allowing the frequency to remain constant regardless of the input and output voltages. Four open-drain power good signals indicate whether the outputs are within their normal range. Fully integrated protection features include over-current protection (OCP), over-voltage protection (OVP), and over temperature protection (OTP).
