Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'CJA' corresponds to the required CDIP package and commercial temperature grade. Check current availability status as this product may be discontinued or subject to last-time buy restrictions. Ensure compatibility with existing board layouts regarding pinout and thermal requirements.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a low-cost, micropower boost regulator is required for inputs between 2.4V and 16.5V. The 25kHz frequency allows for smaller external inductors compared to higher-frequency alternatives. Consider the CDIP package constraints for PCB mounting. Verify that the adjustable output range meets the specific load requirements without exceeding maximum ratings.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MAX4193 family of CMOS DC-DC regulators designed for micropower applications. It shares functional similarities with other Maxim Integrated step-up converters but is distinguished by its specific input range and fixed 25kHz switching frequency. The CJA suffix denotes the commercial temperature range and ceramic dual in-line package variant.
