EVAL-LT8292-GZ

EVAL-LT8292-GZ is an evaluation circuit that features the LT®8292: a parallelable 4-switch synchronous buck-boost controller. The LT8292 regulates the output voltage and output or input current from an input voltage below, equal to, or above the output voltage. With a wide 5.5V to 60V input range and a seamless transition between operating regions, the LT8292 is ideal for automotive, industrial, and telecom systems. The buck-boost peak current mode architecture allows adjustable phase-lockable 100kHz to 650kHz fixed frequency operation or internal spread spectrum operation for low electromagnetic interference (EMI). Additionally, the LT8292 features ISHARE and IGND pins, allowing for multi-IC leaderless current-sharing capabilities for higher-power applications. The EVAL-LT8292-GZ operates from a 36V to 60V input voltage range and generates an output of 48V. A maximum output current of 30A+ allows up to 1400W+ power delivery while achieving efficiencies that exceed 98%.

• Board utilizes two LT8292s in parallel, both set to 400kHz, to achieve high power and efficiency
• 400kHz typ switching frequency at RT = 127kohm
• 98.3 % typ efficiency at VIN = 36V
