The SUW34815B DCDC converter is a popular choice for a variety of applications, ranging from industrial automation to powering consumer electronics. It delivers a high efficiency solution for converting a wide range of DC inputs into regulated DC output voltages and supports rapid transient load current capability. The converter has a wide input voltage range from 8.8V to 28V, up to 15A maximum output current, and output voltage adjustable from 1.2V to 17V. It is also designed to withstand sustained power spikes for temperature stability, and to provide a continuous supply of power, even in harsh environmental conditions.

The SUW34815B is a synchronous buck converter with a fixed 4MHz switching frequency. It uses a high frequency, high efficiency DC/DC power converter topology to produce clean and noise free output voltages. The switching frequency is fixed and adjusted by an external resistor, while the switching duty cycle is varied to maintain the output voltage. The converter is also capable of providing high transient load current.

The SUW34815B uses a integrated integrated feedback and driver circuit for efficient operation at a lower cost. The feedback circuit senses the output voltage, and adjusts the switching duty cycle for precise regulation. The voltage regulation loop can be closed around the input or output of the converter, allowing for adjustable output voltage and high efficiency operation. The internal driver is then utilized to drive the high side and low side MOSFETs for high speed switching. The result is a highly efficient, highly reliable, and cost effective solution for a broad range of power application demands.

The high-efficiency switch mode design of the SUW34815B allows for higher power density with increased current up to 15A, and adjustable output voltage with an accuracy of ±1%. The highly insulated operating temperature range of -40°C to +125°C makes it ideal for non-temperature sensitive applications, and provides high reliability in various operating environments. Additionally, the converter is designed to meet strict noise and EMI requirements with low EMI and fast-transient noise immunity across the full input voltage range.

The SUW34815B DCDC converter has become the go-to choice for power system designers, thanks to its wide input voltage range, adjustable output voltage, high efficiency, high power density, and temperature stability. It is suitable for reliable operation in industrial, automotive, and consumer electronics applications, and is a cost-effective solution for a variety of power solutions.
