VBSD1-S24-S3.3-DIP

DC DC converters are electrical devices used to convert power or electrical signals from one voltage level to another. Examples include voltage regulators, power supplies, switching power supplies, AC to DC converters, DC to DC converters, and battery chargers. They are usually designed to accept a voltage range, output range, or both. DC-DC converters are generally used to increase or decrease the voltage or frequency to meet the requirements of a particular device or system. The VBSD1-S24-S3.3-DIP is a DC-DC converter specifically designed for use in embedded applications.

VBSD1-S24-S3.3-DIP Application Field

The VBSD1-S24-S3.3-DIP is a 3.3V DC to DC converter that is intended for use in embedded systems, such as small mobile phones and other portable devices. It is especially suitable for applications with limited need of voltage sources, such as microcontroller units (MCUs), memory devices, communication systems, and FPGA/ASIC logic systems. The VBSD1-S24-S3.3-DIP provides a low dropout voltage regulator (LDO), buck-boost regulator, secondary rectifier, and step-down regulator in a single, integrated solution. This is ideal for applications that require a efficient power supply, such as mobile phones, PDAs, GPS systems and wireless communication applications.

VBSD1-S24-S3.3-DIP Working Principle

The VBSD1-S24-S3.3-DIP is based on a switched-mode power supply (SMPS) and it uses synchronous rectification to improve performance and reduce cost. The controller includes soft start and overcurrent protection, an adjustable voltage reference, and an on/off switch. It is designed to switch between buck and boost modes depending on the input voltage and the desired output voltage.

The VBSD1-S24-S3.3-DIP uses an internal high-frequency oscillator and two switch controllers. In buck mode, one of the switch controllers (sw1) is used to control the power transfer from the input to the output, while the other (sw2) is used to regulate the output voltage. In boost mode, sw2 is used to transfer the power from the input to the output, while sw1 is used to regulate the output voltage. The primary side FETs are synchronous rectifiers which improves efficiency and reduces output voltage ripple.

The VBSD1-S24-S3.3-DIP is designed to operate in an input voltage range of 2.6V to 5.5V, a maximum output current of 1.5A, and a maximum output voltage of 3.3V. It also features an adjustable output voltage, short circuit protection, and over-temperature protection that can be adjusted to meet the design needs.
