Features & Applications

The NCP1034 is a Low Power PWM Controller with On-Chip Power Switch and Startup Circuits for 48 V Telecom Systems.

The NCP1034 is a high voltage PWM controller designed for high performance synchronous Buck DC-DC applications. The NCP1034 drives a pair of external N-MOSFETs using a programmable switching frequency up to 500 kHz which allows flexibility to tune the operation of the IC to meet system level requirements. An external synchronization feature allows the simplification of system level filter design. The output voltage can be precisely regulated using the internal 1.25 V reference voltage for low voltage applications. Protections such as under voltage lockout and hiccup current limit are provided to give required system level security in the event of a fault.

Key Features:

  • High Voltage Operating up to 100 V
  • Programmable Switching Frequency up to 500 kHz
  • 2 A Output Drive Capability
  • Precision Reference Voltage (1.25 V)
  • Programmable Soft-Start with Prebiased Load Capability
  • Programmable Overcurrent Protection
  • Programmable Undervoltage Protection
  • Hiccup Current Limit Using MOSFET RDS(on) Sensing
  • External Frequency Synchronization
  • 16 Pin SOIC Package
  • This is a Pb-Free Device

Applications:

  • 48 V Non-Isolated DC-DC Converter
  • Embedded Telecom Systems
  • Networking and Computing Voltage Regulator
  • Distributed Point of Load Power Architectures
  • General High Voltage DC-DC Converters
