产品概述 返回TOPrEf嘉泰姆

Internal 20mΩ power and 10mΩ synchronous rectifier switches provide excellent efficiency over a range of applications, especially for low output voltages and low duty cycles. Cycle-by-cycle current limit, input under-voltage lock-out, internal soft-start, output under- and over-voltage protection, and thermal shutdown provide safe operation in all operating conditions.proprietary Instant-PWM™ fast-response, constant-on-time (COT) PWM control method supports high input/output voltage ratios (low duty cycles), and fast transient response while maintaining a near constant operating frequency over line, load and output voltage ranges. This control method provides stable operation without complex compensation and even with low ESR ceramic capacitors.The CXSD62548 is a high-efficiency synchronous step down DC/DC regulator featuring internal power and synchronous rectifier switches capable of delivering 8A of continuous output current and up to 16A peak output current over a wide input voltage range of 4V to 28V.The CXSD62548 is available in a compact QFN3X3-12 package.
