BA033ST

The BA033ST integrated voltage regulator is a step-down dc/dc buck converter suitable for use in applications that require high current and/or high voltages. It provides a voltage range from 5V to 20V and has a current rating up to 3A. The device is designed to minimize external component count and support low power requirements. This makes it highly suitable for a wide range of applications.

The BA033ST operates in two distinct modes: pulse-width modulation (PWM) and pulse frequency modulation (PFM). In the PWM mode, an internal oscillator sets the frequency of the PWM and adjusts the duty cycle depending on the voltage and current requirements. This mode is suitable for applications requiring high efficiency and fast transient response. In the PFM mode, the device pulses at a range of frequencies on the output, depending on the input voltage and current. This mode is well suited to applications operating at light loads, providing efficient power conversion and low ripple.

The BA033ST includes a built-in soft-start feature that gradually sets the output voltage at startup. This ensures a stable supply voltage, protecting the device and connected components. The device also offers a wide input voltage range (5V to 20V) and can operate over the extended temperature range of -40°C to +85°C.

The BA033ST is protected against various fault conditions including overload, short circuit and over temperature. Depending on the fault condition, this device can be configured to either shut down or continue operating in a protected state. Other features include loopback circuit protection, current monitor output and a wide range of output voltage adjustment.

In summary, the BA033ST integrated voltage regulator is a highly efficient, low-cost solution for applications requiring high current and/or high voltage. It offers a wide input voltage range and operates over an extended temperature range. It also provides various protection features, making it an ideal choice for various demanding applications.
