L7987LTR Typical application Circuitry

The L7987LTR is an advanced switching step-down converter integrated circuit (IC) developed by STMicroelectronics. This device offers flexibility and high efficiency, making it a great fit for a wide variety of power supply applications.

Features of L7987LTR:

- Wide Input Voltage Range: The L7987LTR operates over an input voltage range from 4.5V to 61V, which makes it suitable for a wide range of power supply systems.

- Adjustable Output Voltage: It provides an adjustable output voltage from 0.8V to VIN, which further enhances its flexibility in various applications.

- High Efficiency: The low dropout functioning of the L7987LTR maximizes efficiency under light loads.

- Protection Features: The IC integrates comprehensive safety features, including thermal shutdown, short-circuit protection, and overcurrent protection.

Applications of L7987LTR:

The L7987LTR can be used in various power supply systems such as in automotive applications, industrial power supplies, and telecommunications equipment.

Circuit Connection Example - Designing a Step-Down Converter:

1. Input Supply: Connect your main power supply to the VIN and GND pins of the L7987LTR.

2. Output Load: The SW pin of the L7987LTR is connected to the inductor and then to the load through a capacitor. This LC filter is essential for the operation of the step-down converter.

3. Feedback Loop: The low dropout functioning of the L7987LTR maximizes efficiency under light loads. This provides the feedback necessary for the IC to regulate the output voltage.

4. Enable and UVLO: If not in use, attach the enable (EN) pin to VIN. If you want to set an undervoltage lockout (UVLO) level, connect a resistive divider from VIN to the EN pin.

5. Compensation Network: Connect a series RC network from the COMP pin to GND. This network is used for the stability of the control loop.

Design Considerations when using L7987LTR:

- Component Selection: The choice of inductor, output capacitor, and resistive divider is crucial as they directly affect the performance and stability of the system.

- PCB Layout: Careful PCB layout is required for high frequency switching regulators. To reduce parasitic components, the input capacitor, output capacitor, and inductor should be positioned as close to the IC as practicable.

- Thermal Management: As with any power IC, thermal management is an important factor. Depending on the power and ambient temperature, a heatsink might be needed for the L7987LTR.

The L7987LTR is an excellent choice for applications requiring a compact and efficient step-down converter. It is a highly adaptable power management solution because to its wide input voltage range, configurable output voltage, and complete protection features.
