Introduction

The Building Block Solutions – Switchers (BBS-SW) board is a modular demonstration platform designed to evaluate and demonstrate the features of several Microchip Technology monolithic DC-DC switching regulators. The board consists of seven independent sub-modules, each featuring a different DC-DC converter, allowing users to easily test, compare, and integrate these solutions into their own designs.

Sub-Modules Descriptions

  • BBS1: MCP16251 Boost Regulator

    Low Quiescent Current, PFM/PWM Synchronous Boost Regulator with True Output Disconnect or Input/Output Bypass Option

    Ideal for battery-powered applications that require efficient voltage boosting from low input levels.

  • BBS2: MCP16311 Buck Regulator

    30V Input, 1A Output, High-Efficiency, Integrated Synchronous Switch Step-Down Regulator

    Provides high efficiency and a compact solution for stepping down voltages in portable and embedded systems.

  • BBS3: MCP16411 Boost Regulator

    Low IQ Boost Converter with Programmable Low Battery, UVLO and Automatic Input-to-Output Bypass Operation

    Delivers a regulated 3.3V output, suitable for powering microcontrollers and sensors from lower voltage sources.

  • BBS4: MCP1663 Boost Regulator

    High-Voltage Integrated Switch PWM Boost Regulator with UVLO

    Generates a stable 12V output, ideal for applications requiring relatively high voltage rails that are derived from low voltage sources.

  • BBS5: MCP1663 Boost Regulator

    High-Voltage Integrated Switch PWM Boost Regulator with UVLO

    Configured for 24V output, supporting industrial and instrumentation needs.

  • BBS6: MCP1664 LED Driver

    High-Voltage Step-Up LED Driver with UVLO and Open Load Protection

    Supplies 100 mA for driving up to 8 white LEDs (or any other type of LED strings with a combined forward voltage below 25V), suitable for lighting and indicator applications.

  • BBS7: MCP16331 Buck Regulator

    High-Voltage Input Integrated Switch Step-Down Regulator

    Provides a regulated 5V output, commonly used for USB-powered devices and logic circuits.
