The LTM8020IV#PBF is a 200mA, 36V DC/DC μModule® regulator from Analog Devices (formerly Linear Technology).

It's a fully integrated step-down (buck) converter solution that combines the controller, power switches, inductor, and supporting components into a compact, surface-mount package. This design simplifies board layout and reduces design time, making it ideal for space-constrained applications.

The LTM8020IV#PBF is designed for a variety of applications requiring a compact, reliable, and easy-to-use DC/DC power solution:

1. Industrial Automation & Control Systems:

   • Used for Point-of-Load (PoL) regulation for sensors, controllers, and I/O modules due to its wide input range (4V to 36V) and robust performance in industrial environments (-40°C to +85°C).

2. Telecommunications & Networking Equipment:

   • Provides regulated power for low-current loads within communication infrastructure devices, benefiting from its wide input voltage capability.

3. Distributed Power Architectures:

   • Ideal for converting intermediate bus voltages (e.g., 12V or 24V) to lower voltages required by FPGAs, or microprocessors (1.25V to 5V).

4. General Purpose ITE (Information Technology Equipment):

   • Suitable for commercial applications and ITE as listed in its features.

5. Space-Constrained Applications:

   • Its very small μModule package (6.25mm x 6.25mm) and low profile (~2.3mm height) make it suitable for high-density PCB designs and applications where board space is limited.

• High Integration: Saves design time and board space by including the controller, switches, inductor, and compensation circuit in a single package.

• Wide Input Voltage Range (4V to 36V): Can handle a variety of input sources, including unregulated wall adapters, batteries, and industrial power rails.

• Simplified Design: Requires only bulk input and output capacitors to complete the design, reducing external component count.

• Thermal Performance: The LGA package is designed for good thermal performance.
