The BD8303MUV-E2 is a DC/DC switching controller designed by ROHM Semiconductor. It is a pulse width modulation (PWM) controller that can generate a stable output voltage with a single end input voltage in a wide range of input voltage conditions. It is also a very low on resistance main switch device, providing a high efficiency and excellent current-limiting characteristics. This device is designed to operate in extreme conditions, including very cold temperatures and high temperatures, with a wide operating voltage range of 4.5 V to 65 V and an adjustable output voltage of 3.3 V to 16 V. It also offers a low standby current of 0.5 μA, which makes it very suitable for low power applications.

The BD8303MUV-E2 is an ideal choice for applications such as DC/DC converting from 12V/24V battery to 5V/12V DC converter, in-vehicle power converters, and AC/DC converters. Its wide input voltage range and capability to generate a stable output voltage with a single end input voltage makes it suitable for many applications in automotive and industrial settings.

The working principle of the BD8303MUV-E2 is based on pulse width modulation (PWM) and features a zero voltage switching (ZVS) function to achieve higher efficiency. The device uses an internal sensing circuit to determine the output voltage of the converter and then adjusts the duty cycle of the PWM control signal accordingly. The main switch has two control signals with two switches, enabling immediate on/off control of the output voltage. The device also has built-in protection functions to protect the converter from over-current, over-voltage, and over-temperature conditions.

The BD8303MUV-E2 is the ideal solution for a multitude of DC/DC switching controller applications due to its wide input range, excellent current-limiting characteristics, and superior efficiency ratings. With its low standby power consumption, robust control circuitry, and on-chip protection functions, it provides excellent performance and reliable operation in a wide range of operating environments.
