The PM8803 integrates a Power over Ethernet (PoE) interface and a current mode PWM controller to simplify the design of the power supply sections of all powered devices. The PoE/PoE+ interface includes all functions required by the IEEE 802.3at as well as detection, classification, undervoltage lockout (UVLO) and inrush current limitation. The PM8803 specifically performs IEEE802.3at Layer 1 hardware classification, providing the system with an indication of Type 2 PSE successful detection. The PM8803 has been designed to work with power either from the Ethernet cable or from an external power source such as a wall adapter, ensuring the priority of the auxiliary source over the PoE. The DC-DC section of the PM8803 features a programmable oscillator frequency, an adjustable slope compensation, dual complementary low-side drivers, programmable dead time and an internal temperature sensor. The PM8803 targets high-efficiency conversion under all load conditions supporting flyback, forward, forward with active clamp converters and synchronous rectification. https://elecena.pl/product/16940934/pm8803tr-high-efficiency-ieee-802-3at-compliant-integrated-poe-pd-interface-and-pwm-controller 2020-06-04 https://elecena.pl/product/16940934/pm8803tr-high-efficiency-ieee-802-3at-compliant-integrated-poe-pd-interface-and-pwm-controller 2021-04-03 https://elecena.pl/product/16940934/pm8803tr-high-efficiency-ieee-802-3at-compliant-integrated-poe-pd-interface-and-pwm-controller 2021-04-15 https://elecena.pl/product/16940934/pm8803tr-high-efficiency-ieee-802-3at-compliant-integrated-poe-pd-interface-and-pwm-controller 2021-07-16 https://elecena.pl/product/16940934/pm8803tr-high-efficiency-ieee-802-3at-compliant-integrated-poe-pd-interface-and-pwm-controller 2021-12-04 https://elecena.pl/product/16940934/pm8803tr-high-efficiency-ieee-802-3at-compliant-integrated-poe-pd-interface-and-pwm-controller 2022-04-07 https://elecena.pl/product/16940934/pm8803tr-high-efficiency-ieee-802-3at-compliant-integrated-poe-pd-interface-and-pwm-controller 2022-06-13 https://elecena.pl/product/16940934/pm8803tr-high-efficiency-ieee-802-3at-compliant-integrated-poe-pd-interface-and-pwm-controller 2022-06-25 https://elecena.pl/product/16940934/pm8803tr-high-efficiency-ieee-802-3at-compliant-integrated-poe-pd-interface-and-pwm-controller 2023-08-16 https://elecena.pl/product/16940934/pm8803tr-high-efficiency-ieee-802-3at-compliant-integrated-poe-pd-interface-and-pwm-controller 2024-01-16 https://elecena.pl/product/16940934/pm8803tr-high-efficiency-ieee-802-3at-compliant-integrated-poe-pd-interface-and-pwm-controller 2024-02-11 https://elecena.pl/product/16940934/pm8803tr-high-efficiency-ieee-802-3at-compliant-integrated-poe-pd-interface-and-pwm-controller 2024-04-24 https://elecena.pl/product/16940934/pm8803tr-high-efficiency-ieee-802-3at-compliant-integrated-poe-pd-interface-and-pwm-controller 2024-08-16 https://elecena.pl/product/16940934/pm8803tr-high-efficiency-ieee-802-3at-compliant-integrated-poe-pd-interface-and-pwm-controller 2024-11-21 https://elecena.pl/product/16940934/pm8803tr-high-efficiency-ieee-802-3at-compliant-integrated-poe-pd-interface-and-pwm-controller 2025-06-16 https://elecena.pl/product/16940934/pm8803tr-high-efficiency-ieee-802-3at-compliant-integrated-poe-pd-interface-and-pwm-controller 2025-07-04 https://elecena.pl/product/16940934/pm8803tr-high-efficiency-ieee-802-3at-compliant-integrated-poe-pd-interface-and-pwm-controller 2025-10-12 https://elecena.pl/product/16940934/pm8803tr-high-efficiency-ieee-802-3at-compliant-integrated-poe-pd-interface-and-pwm-controller 2026-05-15 https://elecena.pl/product/16940934/pm8803tr-high-efficiency-ieee-802-3at-compliant-integrated-poe-pd-interface-and-pwm-controller 2026-07-11 https://elecena.pl/product/16940934/pm8803tr-high-efficiency-ieee-802-3at-compliant-integrated-poe-pd-interface-and-pwm-controller 2026-07-30
