The PD70201 is an integrated Powered Device (PD) interface and PWM controller designed for use in IEEE 802.3af and IEEE 802.3at applications. It supports 4-pair applications with a power consumption of up to 47.7 W from a single device, and can handle up to 96 W when two devices are used. Key features include detection and classification circuitry, a programmable classification signature, and an integrated 0.6 Ohm isolating MOSFET switch with inrush current limiting. The device operates with a single DC voltage input ranging from 37 V to 57 V and has an adjustable DC-DC switching frequency from 100 kHz to 500 kHz. It also includes a soft-start circuit to manage output voltage rise time, dual under-voltage lockout (UVLO) for reliable operation, and supports low power mode for improved efficiency under light loads. The PD70201 is housed in a compact 32-pin QFN package and is RoHS compliant.
The PD70201 is an integrated Powered Device (PD) Interface and PWM controllers for a DC-DC converter used in IEEE 802.3at Type 2 applications. The PD70201 can be used for IEEE 802.3af, IEEE 802.3at applications. A single PD70201 can be used in 4-pair applications which consumes up to 47.7W.
