AS1383-BWLM-50 is an advanced DC-DC switching regulator from PMIC - Voltage Regulators - DC DC Switching Regulators family.

It is a 50-A, 4-MHz current-mode, synchronous step-down regulator with average current-mode control and input voltage range of 4.1V to 24V, making it suitable for a wide range of applications.

The device is in a scalable power stage, capable of providing output voltage down to 0.8V. It is designed to offer flexibility in setting output voltages in a variety of applications. The DC-DC converter provides high performance, low input ripple, high efficiency, and excellent transient response.

AS1383-BWLM-50 consists of an external primary control and a dedicated secondary controller with a wide input voltage range to support the needs of a variety of design styles. It is also able to provide synchronization to an external clock for stable performance in various operating conditions.

The primary control of AS1383-BWLM-50 provides excellent current-mode regulation and is able to efficiently reduce the ripple of the output voltage. The 1.6 MHz switching frequency helps to reduce the size of the components used in the design of the converter. The secondary controller provides 4mA accuracy for the output voltage and precise regulation to ensure the stability of the output voltage.

The AS1383-BWLM-50 can work in 3 different modes of operation: PWM, PFM, and hybrid. PWM mode is suitable for high efficiency or low standby current requirements. PFM mode is best for light loads and power efficiency. Hybrid mode, on the other hand, works in both PWM and PFM modes depending on the load, simultaneously optimizing converter performance.

The AS1383-BWLM-50 also has an advanced protection feature which includes over-voltage protection, output-over-current protection, thermal protection, and short-circuit protection. This makes the DC-DC converter more reliable and reduces the risk of damage caused by abnormal operation.

In conclusion, the AS1383-BWLM-50 from PMIC - Voltage Regulators - DC DC Switching Regulators offers efficient and stable performance for a wide range of applications. With its wide input voltage range, advanced features, and adjustable output voltage, it provides designers with the ability to select the right solution for their applications.
