LT8302IS8E#WTRPBF

Analog Devices · DC-DC Converters · SOIC-8-EP

LT8302IS8E#WTRPBF from Analog Devices, in a SOIC-8-EP. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 EN/UVLO input Enable and undervoltage lockout input: pulling it below 0.3V shuts the device down, its accurate 1.214V threshold can program a VIN UVLO via a resistor divider with a 2.5µA hysteresis current, and it must be tied directly to VIN if unused.
2 INTVCC power_out Internal 3V linear regulator output that powers the control circuitry and gate driver, must not be overdriven by an external supply, and needs a minimum 1µF ceramic bypass to GND.
3 VIN power_in Input supply pin for 3V to 42V operation that powers the internal circuitry and serves as the reference for the RFB feedback circuit, and it should be locally bypassed to GND.
4 GND power_in Ground pin, which should be connected to the ground plane together with the exposed pad.
5 SW output Drain of the internal 65V, 3.6A DMOS power switch, rated to 65V for transients, so the flyback spike must be derated below 65V and the trace area kept small to reduce EMI and voltage spikes.
6 RFB input Input for the external feedback resistor connected to the transformer primary, with the RFB-to-RREF ratio setting the output voltage, a maximum input current of 200µA, and a voltage limit of VIN − 0.5V to VIN.
7 RREF input Ground-referred reference resistor pin, where the resistor should nominally be 10kΩ and may range from 9.09kΩ to 11.0kΩ for divider ratio selection.
8 TC output Outputs a PTAT voltage of 3.35mV/K (1V at 25°C) that can estimate junction temperature, and a resistor from this pin to RREF compensates the output diode temperature coefficient.
9 GND power_in The exposed pad is GND and must be soldered directly to the PCB ground plane for both electrical and thermal contact.
