Overview
The AZ34063AMTR-E1 is a monolithic switching regulator control circuit manufactured by Diodes Incorporated. It supports Boost, Buck, and Inverting DC-DC topologies within an SOIC-8 surface-mount package. The device operates with an input voltage range of 3 V to 36 V and provides an adjustable output voltage from 1.25 V to 5 V. It delivers a maximum output current of 1.5 A at a fixed switching frequency of 180 kHz. Quiescent current is specified at 4 mA, while the internal oscillator draws 100 uA. The component functions reliably across an industrial temperature range of -40°C to +85°C.
Feature Summary
- Integrates a temperature-compensated reference, voltage comparator, and high-current output switch for complete DC-DC conversion functionality.
- Features a controlled duty cycle oscillator equipped with active current limit circuitry to protect against overload conditions.
- Supports multiple converter topologies including step-up, step-down, and inverting configurations using minimal external components.
Applications
- Battery-powered portable equipment requiring efficient voltage regulation
- DC-to-DC conversion modules for industrial control systems
- General-purpose power supply designs utilizing standard switching regulators
Procurement Notes
Verify component authenticity through authorized Diodes Incorporated channels due to End-of-Life status. Confirm RoHS compliance documentation matches specific manufacturing lot requirements. Validate package integrity upon receipt as moisture sensitivity applies. Cross-reference datasheet revisions to ensure functional compatibility with existing design specifications before integration.
Selection Notes
Select this variant for applications requiring surface-mount assembly in compact designs. The SOIC-8 package facilitates automated placement processes. Ensure thermal management strategies align with the 85°C maximum operating temperature limit. Verify that external inductor and capacitor selections support the 1.5 A peak current capability without saturation or excessive ripple.
Part Context
This component belongs to the AZ34063 series, which serves as a modern replacement for legacy MC34063 devices. The series maintains pin compatibility while offering improved performance characteristics suitable for contemporary power management needs. It integrates essential control logic into a single chip to simplify circuit design and reduce bill of materials complexity.
Replacement Considerations
Direct substitutes include AZ34063AMTR-G1 and AZ34063UP-G1. Verify pinout consistency when transitioning between these variants. Confirm that thermal dissipation requirements remain within acceptable limits for the target application environment.
