LM5143QRWGRQ1 Typical application Circuitry

LM5143QRWGRQ1

The LM5143QRWGRQ1 is a dual-channel synchronous buck controller from Texas Instruments. The device is optimized for high-speed transient applications. This guide will detail the primary pin connection methods. For the most precise details, consult the data sheet and application notes.

1. Power Supply Pins: The PAIN pin is the power supply input and should be connected to a suitable voltage supply according to your application. AKIN provides power to the analog circuits and should be connected to a 5.5V supply. Connect the PGND (Power Ground) and AND (Analog Ground) pins to your system's ground.

2. Switching Node Pins: SW1 and SW2 are the switching node pins for the two buck converters. These pins connect to the drains of the synchronous FET's.

3. Bootstrap Pins: The device uses BOOT1 and BOOT2 pins to create a floating supply for the high-side FET drivers. Connect a bootstrap capacitor from BOOT pin to the corresponding SW pin.

4. Voltage Feedback Pins: FB1 and FB2 pins are the feedback inputs from the output voltage for the two channels. A resistor divider connected to these pins from the output voltage can be used to change the output voltage.

5. Compensation Pins: COMP1 and COMP2 are the compensation network connection points. Connect an RC network to these pins to set the control loop characteristics.

6. Enable and Adjust Pins: EN1 and EN2 pins enable the respective channels, and RT pin adjusts the switching frequency. SS/TRK1 and SS/TRK2 pins are used for soft start and tracking.

7. Synchronization Pin: You may use the SYNC pin to synchronize your device's internal oscillator with an outside clock.

This guide gives a basic approach to interfacing with the LM5143QRWGRQ1 device. However, the specifics of your application may necessitate additional considerations. It's crucial to follow the data sheet and application notes from Texas Instruments to assure correct operation and peak performance of the device.
