TPS650532RGER

Texas Instruments · DC-DC Converters · VQFN-24-EP(4x4)

TPS650532RGER 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 VCC power_in Power supply for digital and analog circuitry; must be connected to the same voltage supply as VINDCDC1/2.
2 VINLDO1 power_in Input voltage for LDO1; recommended operating range 1.5 V to 6.5 V.
3 VLDO1 power_out Output voltage of LDO1; externally adjustable from 1 V to 3.6 V with maximum output current of 400 mA.
4 FB_LDO1 input Feedback input for external voltage divider to adjust VLDO1 output voltage.
5 THRESHOLD input Reset threshold input; voltage exceeding 1 V triggers 100 ms delayed reset pulse.
6 FB_LDO2 input Feedback input for external voltage divider to adjust VLDO2 output voltage.
7 VLDO2 power_out Output voltage of LDO2; externally adjustable from 1 V to 3.6 V with maximum output current of 200 mA.
8 VINLDO2/3 power_in Input voltage for LDO2 and LDO3; recommended operating range 1.5 V to 6.5 V.
9 VLDO3 power_out Output voltage of LDO3; fixed at 1.5 V for TPS650532 variant with maximum output current of 200 mA.
10 RESET tri_state Open-drain active-low reset output with 100 ms reset delay time and 1 mA sink current capability.
11 EN_LDO2 input Enable input for LDO2; logic high enables the LDO, logic low disables and discharges output via 350 Ω resistor.
12 EN_LDO3 input Enable input for LDO3; logic high enables the LDO, logic low disables and discharges output via 350 Ω resistor.
13 FB_DCDC2 input Feedback input to adjust output voltage of DCDC2 between 0.6 V and VIN using external resistor divider.
14 PGND2 power_in Ground pin for converter 2; connect to AGND, PowerPAD, and main ground plane.
15 L2 output Switch pin of converter 2 operating at 2.25 MHz; connected to external inductor (1.5 μH to 2.2 μH) for DC-DC converter 2.
16 VINDCDC1/2 power_in Input voltage for DCDC1 and DCDC2 step-down converters; range 2.5 V to 6 V; must be connected to same supply as VCC.
17 L1 output Switch pin of converter 1 operating at 2.25 MHz; connected to external inductor (1.5 μH to 2.2 μH) for DC-DC converter 1.
18 PGND1 power_in Ground pin for converter 1; connect to AGND, PowerPAD, and main ground plane.
19 FB_DCDC1 input Feedback input to adjust output voltage of DCDC1 between 0.6 V and VIN using external resistor divider.
20 EN_DCDC1 input Enable input for converter 1; active high enables DC-DC conversion with soft start.
21 EN_DCDC2 input Enable input for converter 2; active high enables DC-DC conversion with soft start.
22 EN_LDO1 input Enable input for LDO1; logic high enables the LDO, logic low disables and discharges output via 350 Ω resistor.
23 MODE input Mode selection pin for both converters; low selects Power Save Mode with PFM at light loads, high selects forced PWM mode.
24 AGND power_in Analog ground; connect to PGND1, PGND2, PowerPAD, and main ground plane.
25 PowerPAD power_in Exposed thermal pad for thermal dissipation and ground connection; must be soldered to PCB ground plane.
