Microchip MCP19035 | Demoboard ARD00514

Description

The MCP19035 is a highly-featured, highly-integrated, synchronous buck controller in a space-saving 10-pin DFN 3x3 package that operates from input voltage sources up to 30V. Integrated features include high and low-side MOSFET drivers, fixed-frequency voltage mode control, internal oscillator and reference voltage generator, overcurrent protection circuit for both sides, Power Good circuit and overtemperature protection. A minimal number of external components are necessary to develop a complete, high-performance Synchronous Buck Converter power supply.

Features

• Input Voltage Range: 8V to 26V
• Output Voltage: 5V (can be adjusted by changing one resistor between 3.3V and 5V)
• Maximum output current: 5A
• 93% typical efficiency at 5V/5A output and 24V input
• 600 kHz fixed switching frequency
• Overcurrent protection for high and low-side MOSFETs
• Power Good (PGOOD) output for monitoring the output voltage quality
• Shutdown input for placing the converter in low-power Standby mode
• Undervoltage Lockout (UVLO) with 4.5V and 3.9V typical thresholds

Typical applications

• Industrial 24V rail converters
• High-power LED drivers
• Digital Set-Top boxes
