Product Overview

BD9S402MUF-CE2 is a nano pulse control™, QuiCur™ synchronous buck DC/DC converter integrated FET for automotive. This is a synchronous buck DC/DC converter with built-in low ON resistor power MOSFETs. It can provide current up to 4A. Small inductor is applicable due to high switching frequency of 2.2MHz. It has fast transient response performance due to current mode control. It has a built-in phase compensation circuit. Applications can be created with a few external components. This includes under voltage lockout , short circuit, output over voltage, over current, thermal shutdown protection. Application is automotive equipment, other electronic equipment.
  • Input voltage range from 2.7V to 5.5V, output voltage range from 0.6V to VPVIN x 0.75V(setting)
  • Output current is 4A (maximum), typical switching frequency is 2.2MHz
  • AEC-Q100 qualified, functional safety supportive automotive products
  • Adjustable soft start function, output discharge function
  • Power good output, under voltage lockout protection
  • Wettable flank QFN package
  • Operating temperature range from -40°C to +125°C
  • Typical package (W x D x H) is 3.0 x 3.0 x 1.0mm
