MCP19035 600 kHz High Voltage Synchronous Buck Controller reference design User's Guide
Overview
| Topology | Buck Converter |
| Input voltage | 8-26 V |
| Switching frequency | 550-650 kHz |
| Output 1 | 5 V / 4 A |
| IC revision | A |
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
- High-power LED drivers
- Industrial 24V rail converters
- Digital Set-Top boxes
- USB power ports
- Medium currents Point-of-Load converters, FPGA/DSP power supplies
