Overview
The AZ34063AP-E1 is a monolithic switching regulator control circuit from Diodes Incorporated, designed for DC-DC converter applications. It supports Boost, Buck, and Inverting topologies with an input voltage range of 3 V to 36 V. The device delivers an output current of 1.5 A and features a fixed switching frequency of 180 kHz. It operates within a temperature range of -40°C to +85°C and utilizes an SOIC-8 surface-mount package.
Feature Summary
- Integrates primary DC-DC conversion functions including a temperature-compensated reference, comparator, oscillator, and high-current output switch.
- Supports versatile step-down, step-up, and voltage-inverting configurations using minimal external components.
- Includes active current limiting circuitry to protect the output switch during overload conditions.
Applications
- Step-down (Buck) power supply designs
- Step-up (Boost) power supply designs
- Voltage-inverting converter circuits
Procurement Notes
Verify component authenticity through authorized Diodes Incorporated channels or certified distributors. Confirm RoHS compliance status and check for End-of-Life notices, as availability may be restricted. Ensure storage conditions meet humidity sensitivity requirements prior to assembly.
Selection Notes
Select this component for general-purpose DC-DC conversion requiring adjustable output voltages between 1.25 V and 36 V. Consider the 180 kHz switching frequency for balancing component size and efficiency. Verify that the required load current does not exceed the 1.5 A internal switch limit under all operating conditions.
Part Context
This part belongs to the AZ34063 series, which provides universal DC-DC conversion capabilities. It serves as a cost-effective alternative to discrete solutions by integrating control logic and power switching into a single compact package suitable for space-constrained electronics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other MC34063-compatible devices only if pinout and electrical specifications are verified against official datasheets.
