LM53600MQDSXRQ1

Texas Instruments · DC-DC Converters · WSON-10-EP(3x3)

LM53600MQDSXRQ1 from Texas Instruments, in a WSON-10-EP(3x3). 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 output inductor; SW to GND is rated -0.3 V to VIN+0.3 V, with -2 V and VIN+2 V allowed for up to 200 ns.
2 BOOT input High-side gate driver upper supply rail; connect a 100-nF capacitor from SW to BOOT, which an internal diode charges while SW is low (BOOT to SW maximum 3.6 V).
3 VCC power_out Internal 3-V regulator output that supplies the internal control circuits; for the adjustable version, connect a high-quality 1.0-µF capacitor from this pin to GND (VCC maximum 3.6 V).
4 FB input Adjustable-version feedback input for output voltage only; connect to the output through a voltage divider that sets the output voltage set point (FB to GND range -0.3 V to 5.5 V).
5 BIAS power_in Power source for the VCC regulator in the adjustable version; connect to the output node with a 10-nF bypass capacitor placed immediately adjacent to this pin (BIAS to GND maximum 16 V).
6 RESET output Open-drain reset output (high = regulator OK, low = regulator fault) that needs a current-limiting pull-up resistor to a suitable supply, goes low when EN is low, and is limited to 8 V and 8 mA sink current.
7 EN input Enable input where high turns the regulator on and low turns it off; it can be connected to VIN but must not float (EN to GND maximum 42 V).
8 VIN power_in Input supply to the regulator; connect input bypass capacitors directly between this pin and GND (3.8 V to 36 V input range after startup, 42 V absolute maximum).
9 SYNC/MODE input Multifunction mode input tolerant of voltages up to VIN: a valid external clock forces PWM synchronized to its rising edge, tied high forces PWM at the internal frequency, tied low selects AUTO mode with diode emulation at light load, and it must not float.
10 GND power_in Ground pin that should be bypassed to VIN immediately adjacent to this pin.
11 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
