About This Product

■Summary

The MPM3683-7 is an easy-to-use, fully integrated step-down DC/DC power module with 8A continuous current and 10A peak current. The MPM3683-7 integrates a DC/DC converter, a power inductor, and some basic passive components. The MPM3683-7 has excellent load and line regulation and can deliver output current over a wide input voltage supply range. The MPM3683-7 uses constant on-time (COT) control to provide fast transient response and facilitate loop stabilization. The operating frequency can be easily set to 600kHz, 800kHz, or 1,000kHz by setting MODE, and the MPM3683-7's frequency remains constant regardless of input and output voltages. The MPM3683-7 has an internal soft-start (SS) timer of approximately 1.6ms. This can be increased by placing an additional SS capacitor between TRK/REF and Vo Sense-. An open-drain power-good signal indicates that the output voltage is within the nominal voltage range. The MPM3683-7 has fully integrated, non-latching protection features including overcurrent protection (OCP), overvoltage protection (OVP), undervoltage protection (UVP), and overtemperature protection (OTP). The MPM3683-7 is available in a space-saving QFN-28 (7mm x 7mm x 4mm) package.

■Wide input voltage range from 2.7V

・2.7V to 16V with external 3.3V bias ・4V to 16V with internal bias or external 3.3V bias

■Features and benefits

・Remote sensing of differential output voltage ・Integrated power MOSFET with low RDS (ON) ・Integrated inductor ・Unique switching loss reduction technology ・Constant on time (COT) adaptable to ultra-fast transient response ・Stable with zero ESR output capacitor ・0.5% reference voltage in junction temperature range from 0℃ to 70℃ ・1% reference voltage with junction temperature range of -40℃ to 125℃ - Selectable pulse-skipping or forced continuous conduction mode (CCM) operation ・Excellent load regulation ・Output voltage tracking ・Output voltage discharge ・Active clamping of PGOOD at low level during power failure ・Soft start time programmable from 1.6ms
