Microchip | MCP19035-AAAAE/MF

The MCP19035-AAAAE/MF is a optimized, highspeed synchronous buck controller. Operates from input voltage sources up to 30 V. This controller implements a voltage-mode control architecture with a fixed switching frequency of 300 kHz.

The high switching frequency facilitates uses smaller passive components, including the inductor and input/output capacitors, allowing a compact, high performance power supply solution. It implements an adaptive anti-cross conduction scheme to prevent shoot-through in the external power MOSFET.

Features:

• Input Voltage Range: from 4.5 V to 30 V
• Targeted for Low Voltage Power Trains with Output Current up to 20 A
• High-Speed Voltage Mode, Analog Pulse-Width Modulation Control
• Power Good Output
• Fixed Switching Frequency (fSW): 300 kHz
• Integrated Synchronous MOSFET Drivers
• Multiple Dead-Time Options
• Internal Blocking Device for Bootstrap Circuit
• Integrated Current Sense Capability for Short Circuit Protection
• Internal Overtemperature Protection
