AZ7500BP-E1

DC DC Switching Controllers Overview

The AZ7500BP-E1 is a voltage-mode pulse-width modulation switching regulator control circuit manufactured by Diodes Incorporated. Designed primarily for power supply control, it operates within an input voltage range of 7V to 36V and supports a maximum output current of 200mA. The device features a buck topology with a fixed maximum duty cycle of 45% and a switch frequency range of 1kHz to 200kHz. It utilizes a stable 5V reference voltage trimmed to ±1.0% accuracy for precise output regulation. The component is housed in a 16-pin DIP package and functions across an operating temperature range of -40°C to +85°C.

DC DC Switching Controllers Feature Summary

• Integrated adjustable oscillator supporting master or slave operation modes
• Internal circuitry prevents double pulses at either output terminal
• Selectable single-ended or push-pull output configuration via output control pin

DC DC Switching Controllers Applications

• Switching Mode Power Supplies (SMPS)
• Backlight inverters
• Chargers

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'BP' indicates the DIP-16 through-hole package variant when sourcing. Confirm RoHS compliance status directly from the manufacturer's latest documentation. Check for any End-of-Life notifications or Product Change Notices that may affect long-term availability. Ensure the ordering quantity meets the manufacturer's minimum packaging requirements if applicable.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring a dedicated PWM controller with a 45% duty cycle limit. It is suitable for applications needing a stable 5V reference with high trimming accuracy. Consider the 200mA output drive capability for direct gate driving or external driver interfacing. Evaluate the 16-pin DIP footprint against available PCB space constraints.

DC DC Switching Controllers Part Context

This part belongs to the AZ7500 series of pulse-width modulation control circuits. The series includes variants such as the AZ7500C and AZ7500F, which share similar functional architectures but differ in package types and minor electrical specifications. The AZ7500BP-E1 specifically denotes the DIP-16 package version within this family.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include other AZ7500 series variants like the AZ7500FP-G1, provided the package type matches the design requirements. Verify compatibility regarding reference voltage precision and output drive capabilities before substitution.
