LM536025QPWPRQ1

Texas Instruments · DC-DC Converters · HTSSOP-16-EP

LM536025QPWPRQ1 from Texas Instruments, in a HTSSOP-16-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 SW power_out Regulator switch node that connects to the power inductor; pins 1 and 2 must be connected directly together at the PCB.
2 SW power_out Regulator switch node that connects to the power inductor; pins 1 and 2 must be connected directly together at the PCB.
3 CBOOT power_in Bootstrap supply input for the gate drivers, connected through a high quality 470 nF capacitor to SW.
4 VCC power_out Internal 3.15 V regulator output supplying the internal control circuits; do not connect external loads, and a high quality 3.3 µF capacitor goes from this pin to GND.
5 BIAS power_in Input to the internal voltage regulator, connected to the output voltage point and never grounded, with a high quality 0.1 µF capacitor to GND.
6 SYNC input Synchronization input that locks the regulator switching frequency to the system clock (FSYNC range 1.9 MHz to 2.3 MHz); connect to GND when unused and do not float.
7 FPWM input Mode control input where High selects forced PWM and Low selects auto mode with automatic PFM/PWM transition; do not float.
8 RESET output Open drain reset output that must be pulled up to a suitable supply through a current limiting resistor; High indicates power OK and Low indicates fault, going low when EN is low.
9 FB input Feedback input connected to the output voltage sense point for fixed 5 V and 3.3 V options or to the feedback divider tap for the ADJ option; do not float or ground.
10 AGND power_in Analog ground for the regulator and system, to which all electrical parameters are measured, connected to EP and PGND on the PCB.
11 EN input Enable input where High turns the regulator ON and Low turns it OFF; it can be connected directly to VIN and must not float.
12 VIN power_in Input supply to the regulator, bypassed to PGND with high quality capacitor(s); pins 12 and 13 must be connected directly together at the PCB.
13 VIN power_in Input supply to the regulator, bypassed to PGND with high quality capacitor(s); pins 12 and 13 must be connected directly together at the PCB.
14 N/C unconnected This pin has no connection to the device.
15 PGND power_in Power ground for the internal low side MOSFET, connected to AGND and system ground; pins 15 and 16 must be connected directly together at the PCB.
16 PGND power_in Power ground for the internal low side MOSFET, connected to AGND and system ground; pins 15 and 16 must be connected directly together at the PCB.
17 EP power_in Exposed die attach paddle that must be connected to the ground plane for adequate heat sinking and noise reduction.
