MPM3680 18V 6A Step-Down Power Module in 12x12x4mm QFN The Future of Analog IC Technology DESCRIPTION FEATURES The MPM3680 is an easy-to-use fully integrated Complete 6A DC-to-DC Solution 6A step-down DC/DC power module. It Wide Input Voltage Range from 2.5V: integrates the DC/DC converter, power inductor, -- 2.5V to 18V with External 5V Bias input/output capacitors and the necessary -- 4.5V to 18V with Internal Bias resistors/capacitors in a compact QFN 1% Reference Voltage Over 0C to 70C 12mmX12mmX4mm package. This total power Junction Temperature Range solution needs as few as two external Adaptive COT Control for Ultrafast components (one resistor and one capacitor) to Transient Response work. MPM3680 can deliver 6A output current Programmable Switching Frequency from over a wide input supply voltage range with 200KHz to 1MHz excellent load and line regulation. Support Pre-Bias Start Up Programmable Soft-Start Time with Default The MPM3680 uses Constant-On-Time (COT) 3ms control to provide fast transient response and ease the loop stabilization. Non-latch OCP, OVP and Thermal Shutdown The default under voltage lockout threshold is Output Adjustable from 0.65V to 5V internally set around 4.1V, but a resistor QFN-57 (12mm x 12mm x 4mm) package network on the enable pin can increase this threshold. The MPM3680 has an internal LDO APPLICATIONS to power the control circuits and the integrated Telecom and Networking Systems power devices. This LDO can be disabled by an Base Stations external 5V to boost the efficiency. Servers The MPM3680 has an internal about 3ms soft Personal Video Recorders start (SS) timer. It can be increased with an Flat Panel Television and Monitors extra SS capacitor. An open drain power good Distributed Power Systems signal indicates that the output voltage is within All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. nominal voltage range.
