LM5150QRUMRQ1 Typical application Circuitry

The LM5150QRUMRQ1 is a high-voltage low IQ flyback controller. Manufactured by Texas Instruments, this chip is designed to directly start up from VCC and features an integrated high-voltage start-up regulator.

Characteristics of LM5150QRUMRQ1:

- Start-Up and Operating Voltage: The LM5150QRUMRQ1 operates from an input voltage up to 100V. It provides a constant on-time (COT) current mode control, enabling a fast transient response and easing the loop stabilization.

- Fault Protection: It features a robust suite of fault protection features including output overvoltage protection (OVP), output undervoltage protection (UVP), overload protection (OLP), and thermal shutdown.

- Automotive Qualified: The chip is AEC-Q100 qualified, which allows it to be used in automotive applications.

Typical Applications for LM5150QRUMRQ1

The LM5150QRUMRQ1 is typically used in automotive auxiliary supplies, infotainment, and advanced driver-assistance systems (ADAS). Other potential applications include telecom, servers, and industrial applications.

Detailed Circuit Connection for LM5150QRUMRQ1:

Let's assume we are using the LM5150QRUMRQ1 in a standard automotive auxiliary power supply.

1. Drain Pin (Pin 1): Connect the Drain pin directly to the primary winding of your transformer and to your input voltage source through an appropriate switch.

2. VCC Pin (Pin 2): This pin provides power to the device. Connect it directly to your input source through an appropriately valued resistor.

3. FB Pin (Pin 4): This is the feedback pin and is connected to the auxiliary winding on your transformer through a voltage divider network to monitor the output voltage.

4. SS/EN Pin (Pin 5): The soft start and enable pin can be connected to a capacitor for the soft-start function and can be driven high or left floating to enable the device.

5. GND Pin (Pin 6): Connect this pin directly to your system ground.

Design Considerations:

- Input Voltage: Ensure your input voltage matches the required operating voltage for the device (up to 100V).

- Protection: Consider including protection mechanisms such as fuses on your input line to protect against possible short circuits or overcurrent conditions.

- Thermal Considerations: The LM5150QRUMRQ1 does have an integrated thermal shutdown, but care should be taken to ensure the device is kept within its operational temperature limits.

- Layout: As with any switch mode power supply, care should be taken in layout to minimize noise and maintain good thermal performance.

As always, consult the LM5150QRUMRQ1 datasheet for a complete set of guidelines and circuit recommendations.
