The MCP19035-BAAAE/MF from Microchip Technology is an application-optimized, high-speed synchronous buck controller. It operates from input voltage sources up to 30V and is targeted for low-voltage power trains with output currents up to 20A.
This controller implements a voltage-mode control architecture with a fixed switching frequency of 300 kHz or 600 kHz. The high switching frequency allows for smaller passive components, contributing to a compact, high-performance power supply solution. It features integrated synchronous MOSFET drivers, adaptive anti-cross conduction, and multiple dead-time options for design optimization.
Key features include Power Good output, internal oscillator, reference voltage, overcurrent limit threshold, internal current sense capability for short circuit protection, internal overtemperature protection, and under-voltage lockout (UVLO). The device is available in a 10-DFN (3x3) package and supports surface mount.
Applications for the MCP19035 include point-of-loads, set-top boxes, DSL cable modems, FPGA/DSP power supplies, and PC graphic/audio cards.
