EVAL-LT8624S-AZ-IBB

LT8624S 18V, 4A Synchronous Step-Down Silent Switcher with Ultra-Low Noise Reference Used as an IBB Converter

产品详情

The EVAL-LT8624S-AZ-IBB demonstration board is the inverting buck-boost topology version of the LT8624S, an 18V, 4A synchronous Silent Switcher®3 step-down regulator with ultra-low noise, high efficiency, and power density. The input voltage range of the EVAL-LT8624SAZ-IBB is 2.7V to (18V - |VOUT|). The default demo board setting is -5V for a 2A maximum DC output current with a 5V input, or a 4A maximum DC output current with a 12V input. The LT8624S is a compact, ultra-low noise, ultra-low emission, high efficiency, and high-speed synchronous monolithic step-down switching regulator used as an inverting buck-boost converter. The uniquely designed combination of the ultra-low noise reference and third-generation Silent Switcher architecture enables the LT8624S to achieve both high efficiency and excellent wideband noise performance. A minimum on-time of 12ns allows high VIN to low VOUT conversion at high frequency.
