Monolithic Power Systems (MPS) MPM81204 Step-Down Power Module
Monolithic Power Systems (MPS) MPM81204 Step-Down Power Module is a quad-output step-down module with dual 12A and 5A outputs. It operates at a high efficiency across a wide output current load range. It adopts internally compensated constant-on-time (COT) control to provide a fast transient response and easy loop stabilization.
A single resistor allows the operating frequency to be set to 600kHz, 800kHz, or 1000kHz. This allows the frequency to remain constant, regardless of the input or output voltage. Four open-drain power good signals indicate when the outputs are within their normal voltage range. When the input supply fails to power the MPM81204, the PGOOD pin is clamped to about 0.7V with an external pull-up voltage.
Fully integrated protection features include over-current protection (OCP), over-voltage protection (OVP), and over-temperature protection (OTP). The Monolithic Power Systems (MPS) MPM81204 requires a few readily available, standard external components. It is available in a BGA (9.5mm × 16mm × 4.98mm) package.
