DIODES Incorporated DC DC Switching Controllers AZ7500BUMTR-E1

The AZ7500BUMTR-E1 is a voltage mode pulse-width-modulation (PWM) switching regulator control circuit designed for power supply control applications. It features a stable reference voltage of 4.95V with a trimmed accuracy of ±1.0%, which enhances output voltage regulation. The device supports both single-ended and push-pull output operation, selectable via an output control pin. This regulator includes internal circuitry that prevents double pulsing at either output and offers complete PWM control with a variable duty cycle. The on-chip oscillator can operate in master or slave mode, and the device is compliant with RoHS standards, making it suitable for environmentally conscious designs. The AZ7500B is packaged in a standard SO-16 format and is capable of handling supply voltages from 7V to 36V, with a maximum collector output current of 200mA. It is suitable for applications such as switch-mode power supplies (SMPS), backlight inverters, and chargers.
