Device Overview

Summary

The PD70101 is an integrated Powered Device (PD) Interface and PWM controllers for a DC-DC converter used in IEEE 802.3af applications. The PD70101 can be used for IEEE 802.3af Type 1 applications. The device has several features designed to improve efficiency and reliability:

  • Capacitor
  • Gate drivers
  • Peak current mode control
  • Maximum duty cycle
  • Soft-start circuit
  • Low voltage protection warning and monitoring

Start your PoE PD power supply design using Microchip MPLAB® Analog Designer.
