Overview
The AZ34063UP-E1 is a monolithic switching regulator control circuit manufactured by Diodes Incorporated. It supports Buck and Boost topologies with an input voltage range of 3 V to 36 V and adjustable output from 1.25 V to 36 V. The device delivers up to 1.5 A output current at a fixed switching frequency of 180 kHz. Key electrical parameters include a maximum operating temperature of +85 C, minimum of -40 C, static current of 100 uA, and operating supply current of 4 mA. It is housed in a DIP-8 through-hole package.
Feature Summary
- Integrates internal temperature-compensated reference, voltage comparator, controlled duty cycle oscillator, driver, and high-current output switch.
- Features active current limit circuitry for robust protection during operation.
- Supports versatile DC-DC conversion including step-up, step-down, and inverting configurations.
Applications
- Battery-powered systems requiring efficient voltage regulation
- General-purpose DC-to-DC converter designs
- Simple power supply circuits utilizing external passive components
Procurement Notes
Verify component authenticity as the AZ34063UP-E1 is listed as End of Life (EOL) by the manufacturer. Confirm availability through authorized distributors or secondary markets. Ensure the specific suffix matches required specifications, as variations may exist within the family. Check RoHS compliance details on official documentation before integration into new designs.
Selection Notes
Select this component for applications requiring a low-cost, single-output switching regulator with moderate current capabilities. The DIP-8 package suits through-hole prototyping or manufacturing environments. Consider the fixed 180 kHz frequency when designing external inductors and capacitors. Evaluate thermal performance within the specified -40 C to +85 C operating range for the intended environment.
Part Context
This part belongs to the AZ34063 series, which are direct replacements for the industry-standard MC34063 devices. The series provides a compact solution for basic DC-DC conversion needs. Diodes Incorporated offers various package options, including surface-mount variants like the AZ34063AMTR-E1, alongside the through-hole DIP-8 configuration found in this model.
Replacement Considerations
Direct pin-compatible substitutes include the MC34063A/E series from other manufacturers such as STMicroelectronics or ON Semiconductor. Verify that alternative sources maintain identical electrical characteristics, particularly the 1.5 A output current and 180 kHz switching frequency, to ensure circuit compatibility without redesign.
