- Designed for flexible and cost-effective buck regulator implementations
- Voltage-mode switching power supply controller functionality
DC DC Switching Controllers Applications
- Buck (step-down) regulator supply design
- Voltage-mode SMPS controller circuits
- Positive output DC/DC switching regulators
DC DC Switching Controllers Procurement Notes
Verify the manufacturer designation as Microsemi Corporation or Microchip Technology, as corporate transitions may affect labeling. Confirm the specific suffix 'CDM' corresponds to the 8-SOIC package variant. Check for obsolescence status or lifecycle notices from official distributors, as legacy components may have limited availability or require alternative sourcing strategies.
DC DC Switching Controllers Selection Notes
Select this component when a dedicated voltage-mode PWM controller for buck topologies is required. Ensure the application supports the monolithic IC architecture rather than discrete solutions. Verify that the 8-SOIC footprint fits the PCB layout constraints. Consider thermal management requirements associated with the SOIC package in high-current regulator designs.
DC DC Switching Controllers Part Context
The LX1682 series includes related models such as the LX1681, sharing similar monolithic PWM controller architectures. These devices are part of Microsemi's portfolio for power management integrated circuits. The LX1682CDM specifically denotes the commercial grade version in the standard 8-pin small outline integrated circuit package format.
