LM53601AQDSXTQ1

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

LM53601AQDSXTQ1 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 output Regulator switch node. Connect to output inductor.
2 BOOT power_in High side gate driver upper supply rail; connect 100-nF capacitor from SW to BOOT with internal diode charging capacitor while SW is low.
3 VCC power_out Internal 3-V regulator output used as supply to internal control circuits; connect high quality 1.0-μF capacitor from this pin to GND for adjustable versions.
4 FB input Feedback input for adjustable version only; connect to output through voltage divider which determines output voltage set point.
5 BIAS power_in Power source for VCC regulator in adjustable version; connect to output node and place 10-nF bypass capacitor immediately adjacent to this pin.
6 RESET output Open drain reset output; high indicates regulator OK, low indicates regulator fault; connect through current limiting pull up resistor to suitable voltage supply.
7 EN input Enable input to regulator; high enables operation, low disables; can be connected to VIN but do not float.
8 VIN power_in Input supply to regulator with range 3.8V to 36V after startup; connect input bypass capacitors directly between this pin and GND.
9 SYNC/MODE input Multifunction mode control input tolerant to input voltage; external clock synchronization or tied high selects forced PWM mode, tied low selects AUTO mode with diode emulation.
10 GND power_in Ground connection; bypass to VIN immediately adjacent to this pin.
11 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
