Working Principle

The MIC9130BQS-TR is a pulse-width modulation (PWM) regulator which produces a stable output voltage using a feedback loop to monitor and adjust the output voltage. The device works by switching power transistors ON and OFF at a predetermined frequency, with the duty cycle of the ON/OFF cycle adjusted according to the output voltage.When the input voltage is below the output voltage the device switches ON the power switch and when the input voltage rises above the output voltage the device switches OFF the power switch. By adjusting the ON and OFF times, the output voltage can be regulated.The device is packaged in a 4mm×4mm package. The device is protected by an over-current protection, a short-circuit protection and an over-voltage protection, allowing it to safely operate in harsh automotive and industrial environments.The MIC9130BQS-TR also features TTL compatible enable and disable controls, allowing for critical power supply sequencing requirements. The device can be configured for operation in constant current or constant voltage modes.

Conclusion

The MIC9130BQS-TR is an integrated pulse-width modulation (PWM) regulator designed to provide adjustable current and voltage regulation with high efficiency and low noise. It offers wide input voltage range, high efficiency and low noise. The device is suitable for use in a wide range of automotive and industrial applications. It is packaged in a 4mm×4mm TQFN, and offers adjustable output current and voltage regulation, safety class protections, enable and disable controls and configurable operation modes.
