PMIC - Voltage Regulators - DC DC Switching Regulators

The LT8650SHV-1#PBF is an advanced high-voltage, low-voltage DC-DC switching regulator. It is designed for applications where high power conversion efficiency with low-voltage power delivery are needed. The LT8650SHV-1#PBF can efficiently convert a wide input voltage range from 4V to 45V down to a very low output voltage of 0.8V.The LT8650SHV-1#PBF supports up to 5A output current with up to 95% conversion efficiency and up to 10kHz switching frequency. It also supports a Shutdown and diode emulation mode of operation. Other features include an adjustable current limit, programmable switching frequency and a programmable soft-start feature. The device also supports power supply sequencing and power optimization of multiple point-of-load (POL) boards.The LT8650SHV-1#PBF device is designed for use in applications such as mobile phones, tablets, phablets, monitors, TV’s and other hand-held and mobile electronics. It supports power dissipation from 0.14W to 0.5W up to 95°C ambient temperature and it is suitable for operation from -40°C to +125°C.The LT8650SHV-1#PBF features a synchronous switching architecture that generates high efficiency and low power dissipation. The outputs are controlled using a high-frequency switch that operates at up to 10kHz. Other features include programmable soft-start, adjustable current limit, voltage limit and fault protection.The LT8650SHV-1#PBF is powered by a wide input voltage range from 4V to 45V. The low-voltage input reduces the component count and associated cost, while providing high power efficiency when operating at low output current. The device also supports power supply sequencing, power optimization and integrated circuit protection.The LT8650SHV-1#PBF can also operate in diode emulation mode, providing the highest efficiency of operation. When the device operates in this mode, the internal PMOS-switch replaces the Schottky diode with a low forward voltage drop and reduced power dissipation. The diode emulation mode of operation is suitable for applications that need to operate at low output current and low-voltage with high power efficiency.The LT8650SHV-1#PBF can also support a variety of application specific features such as adjustable output programming, programmable soft-start, delay on rising, bias current reduction and e-fuse settings. These features can be used to customize the device to fit the needs of specific applications.In conclusion, the LT8650SHV-1#PBF is a high-performance DC-DC switching regulator. It supports a wide input voltage range, high switching frequency, power supply sequencing and integrated circuit protection. The device is ideal for applications that need to operate at very low-voltage and high power efficiency.
