JW5015AESOP#TRPBF

JoulWatt Tech · DC-DC Converters · ESOP-8

JW5015AESOP#TRPBF from JoulWatt Tech, in a ESOP-8. 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 SW output Switching node that supplies power to the output; connect the output LC filter from SW to the load, with SW rated -0.3V to 44V absolute maximum.
2 BST passive Bootstrap pin for the top switch; a 0.1uF or larger capacitor must be connected between BST and SW, and BST is rated SW-0.3V to SW+5V.
3 BIAS/VD power_out Output of the internal LDO; a capacitor of 2.2uF or larger should be connected from VD to ground.
4 FB input Output feedback pin that senses the output voltage and is regulated by the control loop to 0.8V; connect a resistive divider at FB.
5 NC unconnected No connection.
6 GND power_in Ground; must be connected to the exposed pad and to pin 9 as close as possible.
7 EN input Drive high to turn the regulator on and low to turn it off; the device enters shutdown when EN is driven below 0.3V, and EN is rated -0.3V to 44V absolute maximum.
8 VIN power_in Input voltage pin supplying the IC; connect a 3.6V to 40V supply and bypass VIN to GND with a suitably large capacitor.
9 GND power_in Ground exposed pad; the pad and pin 6 must be connected to GND, and pin 9 must be connected to pin 6 as close as possible.
