The LMZM23600 integrated-inductor power module is specifically designed for space-constrained industrial applications. The device is available in two fixed output voltage options of 5 V and 3.3 V, and an adjustable (ADJ) output voltage option supporting a 1.2-V to 15-V range. The LMZM23600 has an input voltage range of 4 V to 36 V and can deliver up to 500-mA of output current. This power module is extremely easy to use, requiring only two external components for a 5-V or 3.3-V output design. All aspects of the LMZM23600 are optimized for performance driven and low EMI industrial applications with space-constrained needs. An open-drain, Power-Good output provides a true indication of the system status and negates the requirement for an additional supervisory component, saving cost and board space. Seamless transition between PWM and PFM modes along with a no-load supply current of only 28 µA ensures high efficiency and superior transient response for the entire load-current range. For easy output current scaling the LMZM23600 is pin-to-pin compatible with the 1000-mA output current capable LMZM23601.

NO. | NAME | ||
1 | GND | G | Ground for all circuitry. Reference point for all voltages. |
2 | MODE/SYNC | I | This pin is a
multifunction mode control input which is tolerant of voltages up to
the input voltage. With this input tied LOW, the device is in Auto PFM mode with automatic transition between PFM and PWM with diode emulation at light load. TI recommends this mode when the application requires high efficiency at light load. With this input tied HIGH, the device is in forced PWM mode. The device switches at the internal clock frequency. TI recommends this mode when the application requires constant switching frequency across the entire load current. With a valid synchronization signal at this pin, the device switches in forced PWM mode at the external clock frequency and synchronized with it at the rising edge of the clock. Do not float this pin. |
3 | VIN | P | Input supply to the regulator. Connect a high-quality bypass capacitors directly to this pin and the GND pin (pin 1). |
4 | EN | I | Enable input to the regulator. HIGH = ON, LOW = OFF. This pin can be connected to VIN. Do not float. |
5 | PGOOD | O | Open-drain, power-good output. Connect to a suitable voltage supply through a current limiting resistor. HIGH = power is good, LOW = fault. This output terminal is LOW when EN is LOW. |
6 | VOUT | O | Output voltage terminal. This pin is internally connected to one terminal of the integrated inductor. Connect an output filter capacitor from VOUT to GND and place the capacitor as close as possible to the VOUT pin. |
7 | FB | I | Feedback input
to the regulator. If using the fixed 3.3-V or 5-V options of the device, connect this pin to the positive end of the output filter capacitor (the VOUT node). If using the adjustable output option of the device connect this to the feedback voltage divider and keep this node as small as possible on the board layout. |
8 | DNC | O | Do not connect. Leave floating. This pin provides access to the internal VCC voltage of the device. |
9 | DNC | O | Do not connect. Leave floating. This pin provides access to the internal BOOT voltage for the high side MOSFET driver. |
10 | DNC | O | Do not connect. Leave floating. This pin provides access to the internal SW voltage of the device. |
Thermal Pad | — | G | This terminal is internally connected to GND and provides a wide thermal connection from the IC to the PCB. Connect to electrical ground plane for adequate heat sinking. |
