Switching Converters for Step-Down Voltage (Buck)

We provide a range of pin-compatible, DC-DC step-down switching regulators that can lower your system's Bill of Materials (BOM) cost. Use the pin-selectable and I²C-configurable features to optimize your system’s performance, simplify layout requirements and reduce the number of external components.

The MCP1636x family of devices contains fixed-frequency, step-down voltage (Buck) DC-DC converters that operate from input voltage sources up to 48V. These highly integrated, high-efficiency devices come in compact eight-lead 3 × 3 mm VDFN wettable flank packages and include features such as high-side switches, fixed-frequency peak current mode control, internal compensation, power good, peak current limit and overtemperature protection.

The MCP16331 is a highly integrated, high-efficiency, fixed frequency, step-down DC-DC converter in a popular 6-pin SOT-23 or 8-pin 2 × 3 TDFN package that operates from input voltage sources up to 50V. Integrated features include a high side switch, fixed frequency Peak Current Mode Control, internal compensation, peak current limit and overtemperature protection. Minimal external components are necessary to develop a complete step-down DC-DC converter power supply.

The MIC24066/7 is a family of commercial 36V synchronous switching regulators that support a wide input range of 4.5–36V and deliver 6A of load current. These integrated Field-Effect Transistor (FET) switching regulators feature an enhanced high-voltage Constant-On-Time (COT) controller that is packaged with a pair of N-channel FETS with improved avalanche rating.
