AZ34063CMTR-G1

Overview

The AZ34063CMTR-G1 is a monolithic switching regulator control circuit from Diodes Incorporated, designed for DC-DC converter applications. It integrates an internal temperature-compensated reference, voltage comparator, controlled duty cycle oscillator with active current limit, driver, and high-current output switch. The device supports Boost, Buck, and Inverting topologies with an input voltage range of 3V to 36V. It delivers an output current of up to 1.5A and features an adjustable output voltage from 1.25V to 36V. Operating at a fixed switching frequency of 180kHz, it maintains a low standby current of 100µA. The component operates within a temperature range of -40°C to +85°C and is housed in an SOIC-8 surface-mount package.

Feature Summary

• Integrates primary DC-DC converter functions including a temperature-compensated reference and active current limiting circuit
• Supports versatile conversion topologies including boost, buck, and inverting configurations
• Features a high-current output switch capable of delivering up to 1.5A load current
• Maintains low power consumption with a standby current specification of 100µA

Applications

• Step-up (Boost) converter circuits
• Step-down (Buck) converter designs
• Inverting voltage converter implementations

Procurement Notes

Verify the specific suffix 'G1' against the manufacturer's latest documentation to confirm RoHS compliance status and exact pinout configuration. Ensure the SOIC-8 package dimensions match your PCB footprint requirements. Confirm that the 180kHz switching frequency aligns with your electromagnetic interference constraints and inductor selection criteria before finalizing procurement.

Selection Notes

Select this component when a single-chip solution for adjustable voltage regulation is required across a wide input range. It is suitable for applications needing moderate output currents up to 1.5A without external pass transistors. Consider the fixed 180kHz frequency for passive component sizing. Verify thermal performance within the specified operating temperature range for your specific enclosure design.

Part Context

This part belongs to the AZ34063 series of switching regulators manufactured by Diodes Incorporated. It serves as a direct functional equivalent to legacy IC-563/34063 devices but offers improved integration and efficiency. The series is categorized under PMIC - Power Management ICs, specifically switching voltage regulators, providing a compact alternative to discrete switching solutions.

Replacement Considerations

Direct replacements include other variants within the AZ34063 family such as AZ34063UMTR-G1 or AZ34063AMTR-E1, provided package and electrical specifications are compatible. Legacy equivalents like the MC34063 may require external component adjustments due to differences in internal architecture and current handling capabilities.
