EVM3683-7-QN-01A 16V, 8A DC/DC Power Module Evaluation Board DESCRIPTION FEATURES Wide Input Voltage Range from 2.7 V: The EVM3683-7-QN-01A Evaluation Board is -- 2.7 V to 16 V with External 3.3 V Bias designed to demonstrate the capabilities of MPS -- 4 V to 16 V with Internal Bias or External MPM3683-7.The MPM3683-7 is an easy-to-use 3.3 V Bias fully integrated peak10A, continuous 8A step- Differential Output Voltage Remote Sense down DC/DC power module. MPM3683-7 can Peak 10A, Continuous 8A Output Current deliver output current over a wide input supply voltage range with excellent load and line Adaptive Constant-on-Time (COT) for regulation. Ultrafast Transient Response Selectable Pulse Skip or Forced CCM The MPM3683-7 uses Constant-On-Time (COT) Operation control to provide fast transient response and Output Voltage Discharge ease the loop stabilization. Pre-Bias Start-Up The operating frequency is set easily to 600 Selectable Switching Frequency from kHz, 800 kHz, or 1000 kHz with the MODE 600kHz, 800 kHz, and 1000 kHz configuration, allowing the MPM3683-7 Non-Latch OCP, UVP, UVLO, Thermal frequency to remain constant regardless of the Shutdown, and OVP. input/output voltages. Output Adjustable from 0.6 V to up to 5.5 V The MPM3683-7 is available in a space-saving Max. QFN-28 (7mmx7mmx4mm) package.
