Introducing the LTC3788IUFDPBF from Linear Technology

The LTC3788IUFDPBF is a high-performance, dual 2-phase synchronous step-up DC/DC controller that is engineered to provide a robust power management solution for a wide array of applications. This advanced component from Linear Technology is designed to drive N-channel MOSFETs in a voltage range of 4.5V to 38V, making it an ideal choice for systems requiring efficient power conversion and distribution.

One of the standout features of the LTC3788IUFDPBF is its phase-lockable fixed frequency, ranging from 50kHz to 900kHz, which allows for optimization of efficiency, performance, and component size. The device also supports selectable Continuous Conduction Mode (CCM) or Discontinuous Conduction Mode (DCM), enabling designers to tailor the operation mode to the specific needs of their power supply design, whether prioritizing efficiency or reducing output ripple and noise.

The LTC3788IUFDPBF boasts a powerful 1.1Ω onboard gate drivers, which provide the necessary drive strength to handle large power MOSFETs with ease. This ensures that the power supply can deliver the required power levels while maintaining high efficiency and fast transient response. The device also features current mode control, providing excellent line and load regulation as well as ease of loop compensation.

For added flexibility, the LTC3788IUFDPBF includes a tracking input, allowing for smooth tracking and sequencing of the output voltage to other voltage rails. Its output voltage can be set with a resistor divider, and the precise 0.8V reference with a ±1% accuracy over the full temperature range ensures consistent performance.

The LTC3788IUFDPBF is housed in a 4mm x 5mm QFN-28 package, making it compact and suitable for space-constrained applications. Its robust design includes overvoltage, overcurrent, and overtemperature protection, safeguarding your system against a range of potential faults.

Whether you're designing power systems for telecommunications, industrial, automotive, or computing applications, the LTC3788IUFDPBF provides a reliable and efficient solution that can meet the rigorous demands of modern electronic devices.
