178010550

Evaluation board for 171010550 VDMM (Variable Step Down MicroModule) MagI3C power module. VDMM MagI3C MicroModule provides a fully integrated DC-DC power supply including the switching regulator with integrated MOSFETs, compensation and shielded inductor in one package. The 171010550 offers high efficiency and delivers up to 1.2A of output current. It operates with an input voltage from 2.5V to 5.5V and is designed for a small solution size. The selectable forced PWM or PFM/PWM mode allows for the choice between high efficiency and low output voltage ripple at light load. This module has integrated protection circuitry that guards against thermal overstress with thermal shutdown and protects against electrical damage using overcurrent, short-circuit and undervoltage protections.

• Peak efficiency up to 96%
• Output voltage range from 0.8V to 5.5V
• 25µA typical quiescent current
• Low output voltage ripple of ±6mV typ
• Fixed switching frequency of 4MHz
• Constant on-time control, synchronous operation
• Selectable forced PWM or PFM/PWM mode
• Undervoltage lockout protection (UVLO), embedded soft-start
• Thermal shutdown, short-circuit protection, cycle-by-cycle current limit
