NCP81232: Multi-Phase Controller with Dual Loop Capability, Configurable, DrMOS Compatible

具体说明: The NCP81232 can be configured as a single or dual...
  • The NCP81232 can be configured as a single or dual output regulator intended to operate with DrMOS power stages. This IC can be set with up to 8 unique output configurations that offer the operate as a single output with operation from a single to quad phases or as a dual output device with phase combinations of 3+1, 2+2, 2+1, and 1+1. This controller offers differential current sense and voltage sense for greater accuracy. The device supports DCR current sense or can accommodate an IMON signal from the DrMOS. The parts offer protection against overcurrent, over/undervoltage, and overtemperature protection.
  • 特性
  • 4.5V to 24V input with internal bias - Optimized for 12V and 5V bus voltage designs
  • Adjustable output from 0.6V to 5V - Low voltage capability to power core voltages
  • Adjustable switching frequency from 200kHz to 1.2MHz - Allows optimization of design for size and efficiency
  • PWM output compatible to 3.3V and 5V DrMOS - Compatible with standard DrMOS
  • 8 Configurations (single or dual output) - Flexibility allows for partitioning of power
  • Differential output sense - Maintain voltage accuracy with high current design
  • Differential current sense - Allows DCR current sense (or from Iout of DrMOS)
  • Overcurrent, Over/Undervoltage, and Thermal protection - Protected against faults
