TPS65101RGER

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

TPS65101RGER 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; a small capacitor is connected to this pin.
2 ENR input Enable pin of the linear regulator controller; it must be terminated and not left floating, with logic high enabling the regulator and logic low putting it in shutdown.
3 EN input Enable pin of the device; it must be terminated and not left floating, with logic high enabling the device and logic low shutting it down.
4 FB1 input Feedback pin of the boost converter (VO1).
5 FB4 input Feedback pin of the linear regulator controller, which is set to a fixed output of 3.3 V or 3 V depending on the version.
6 BASE output Base drive output for the external transistor; if the linear regulator is not needed, pull this pin against VIN.
7 VIN power_in Input voltage pin of the device, specified for 2.7 V to 5.8 V.
8 SW passive Switch pin of the boost converter; voltage on SW is rated -0.3 V to 20 V absolute maximum.
9 SW passive Switch pin of the boost converter; voltage on SW is rated -0.3 V to 20 V absolute maximum.
10 PGND power_in Power ground; the PowerPAD / exposed thermal die must be connected to the power ground pins.
11 PGND power_in Power ground; the PowerPAD / exposed thermal die must be connected to the power ground pins.
12 SUP input Supply pin of the positive and negative charge pumps, boost converter gate drive and VCOM buffer; it must be connected to the boost converter output and not to any other voltage source, and a bypass capacitor is not recommended directly on this pin.
13 VCOM output VCOM buffer output; voltage on VCOM is rated -0.3 V to 15 V absolute maximum.
14 VCOMIN input Positive input terminal of the VCOM buffer; when the buffer is not used it can be connected to GND to reduce the overall quiescent current.
15 FB3 input Feedback pin of the positive charge pump.
16 OUT3 output Positive charge pump output (VO3); voltage on VOUT3 is rated -0.3 V to 30 V absolute maximum.
17 C2+ passive Positive terminal for the charge pump flying capacitor; this pin should be left open if the device runs in voltage doubler mode.
18 C2-/MODE passive Negative terminal of the charge pump flying capacitor and charge pump MODE pin; the flying capacitor connected here selects voltage tripler mode, while connecting this pin to GND (flying capacitor removed) selects 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; voltage on DRV is rated -0.3 V to 15 V absolute maximum.
22 GND power_in Ground pin of the device.
23 REF output Internal reference output, typically 1.23 V; voltage on REF is rated -0.3 V to 4 V absolute maximum.
24 FB2 input Feedback pin of the negative charge pump.
25 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
