The EM3707/A/B is a high-efficiency step-down buck converter module available now from distributor Ineltek.

It is based on ETAs ETA3707 buck converter with built-in power MOSFETs, inductorand capacitor.

The integrated structure simplifies the power system design.

The EM3707/EM3707T can provide programmable output voltages from 1.2V to 3.3V, and capable to deliver up to 1A of output current.

The EM3707A/EM3707AT can provide programmable output voltages from 0.7V to 3.1V, and capable to deliver up to 500mA of output current.

The EM3707B/EM3707BT can provide programmable output voltages from 0.5V to 1.9V, and capable to deliver up to 500mA of output current.

The core features of the whole series cover:

  • Wide input voltage range: 2.1V-5.5V
  • Less than 450nA typical quiescent current
  • Integrated MOSFETs, inductor and capacitor
  • Up to 1A(EM3707) and 500mA(EM3707A/B) maximum output current
  • Up to 94% efficiency
  • 2MHz switching frequency
  • Programmable output voltage
  • Adaptive COT control
  • Ultra-fast load transient response
  • High Efficiency PFM mode at light load
  • Over current protection
  • Over temperature protection
  • Similar DFN3x3 package with 1.2mm and 0.91mm package thickness
