Microchip Technology, Inc. PMIC - PMIC - Voltage Regulators - DCDC Switching Controllers - MCP19035T-AAABE/MF MCP19035T-AAABE/MF

The MCP19035T-AAABE/MF is a high-speed synchronous buck controller designed for low-voltage power applications. It operates with an input voltage range of 4.5V to 30V and can deliver output currents up to 20A. The controller features a voltage-mode control architecture with selectable switching frequencies of 300 kHz or 600 kHz, which allows for the use of smaller passive components, enhancing the compactness of power supply designs. Key features include integrated synchronous MOSFET drivers, multiple dead-time options, and an internal blocking device for the bootstrap circuit. The MCP19035 also incorporates essential protection mechanisms such as overcurrent limit, overtemperature protection, and under-voltage lockout (UVLO). Additionally, it provides a Power Good output for fault detection and simplifies sequencing in power management applications. The device is packaged in a 10-lead DFN (3x3 mm) format, making it suitable for various applications, including point-of-load converters, set-top boxes, DSL modems, and power supplies for FPGAs and DSPs.
