Product Overview
LT4295 is a IEEE 802.3af/at/bt-compliant powered device (PD) interface controller with a switching regulator controller. The T2P output indicates the number of classification events received during IEEE 802.3bt-compliant mutual identification and negotiation of available power. It supports both forward and flyback power supply topologies. The flyback topology supports No-Opto feedback. Auxiliary input voltages can be accurately sensed with just a resistor divider connected to the AUX pin. It utilizes an external, low RDS(on) N-channel hot swap MOSFET and supports the LT4320/LT4321 ideal diode bridges, to extend the end-to-end power delivery efficiency and eliminate costly heat sinks. It is used in applications such as high power wireless data systems, outdoor security camera equipment, commercial and public information displays, high temperature applications etc.
- Supports upto 71.3W PDs
- Superior surge protection (100V Absolute Maximum)
- No-opto flyback operation
- Auxiliary power support as low as 9V
- Easy migration of LTPoE++® PDs to IEEE 802.3bt PDs
- Pin compatible with LT4276A/B/C
- VCC regulation voltage is 7.6V typical at (TJ = 25°C, VVPORT = VHSSRC = VVIN = 40V)
- Switching frequency is 300KHz typical at (45.3Kohm from ROSC to GND)
- Operating junction temperature is -40°C to 125°C
- Package style is 28-lead plastic QFN
