TPS65145RGER

Texas Instruments · LCD Drivers · VQFN-24-EP(4x4)

TPS65145RGER from Texas Instruments, in a VQFN-24-EP(4x4). 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 COMP passive Compensation pin for the main boost converter with a small capacitor connected for stability.
2 ENR input Enable pin of the linear regulator controller; logic high enables and logic low puts the regulator in shutdown.
3 EN input Enable pin of the device; logic high enables and logic low shuts down the device.
4 FB1 input Feedback pin of the boost converter.
5 FB4 input Feedback pin of the linear regulator controller set to fixed output voltage of 3.3 V or 3 V depending on device version.
6 BASE output Base drive output for the external transistor.
7 VIN power_in Input voltage pin of the device operating from 2.7 V to 5.8 V.
8 SW input Switch pin of the boost converter connecting to external inductor and diode.
9 SW input Switch pin of the boost converter connecting to external inductor and diode.
10 PGND power_in Power ground connection.
11 PGND power_in Power ground connection.
12 SUP power_in Supply pin for positive and negative charge pump, boost converter, and gate drive circuit that must connect to main boost converter output only.
13 PG output Open-drain power good output indicating when all outputs VO1, VO2, VO3 are within 10% of nominal voltage, going low when one output falls below 10% of nominal voltage.
14 GND power_in Ground connection.
15 FB3 input Feedback pin of positive charge pump.
16 OUT3 output Positive charge pump output.
17 C2+ passive Positive terminal for the charge pump flying capacitor that must be left open for voltage doubler mode operation.
18 C2-/MODE passive Negative terminal of the charge pump flying capacitor and MODE pin; flying capacitor connection enables voltage tripler mode while connection to GND enables voltage doubler mode.
19 C1+ passive Positive terminal of the charge pump flying capacitor.
20 C1- passive Negative terminal of the charge pump flying capacitor.
21 DRV output External charge pump driver output.
22 GND power_in Ground connection.
23 REF output Internal reference output with typical value of 1.23 V.
24 FB2 input Feedback pin of negative charge pump.
25 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
