The SC4601 is a voltage mode step down (buck) regulator controller that provides accurate high efficiency power conversion from input supply range 2.75V to 5.5V. A high level of integration reduces external component count and makes it suitable for low voltage applications where cost size and efficiency are critical.

Features


  • Progammable switching frequency up to 600KHz
  • BiCMOS voltage-mode PWM controller
  • 2.75 V to 5.5 V input voltage range
  • Output voltages as low as 0.8 V
  • ± 1% reference accuracy
  • Sleep mode (Icc = 10 µA typ)
  • Lossless adjustable over-current protection
  • Combination pulse-by-pulse & hiccup-mode current limit
  • High-efficiency synchronous switching
  • Up to to 100% duty cycle range
  • Synchronization to external clock
  • 10-Pin MSOP surface mount package. Available in Lead-free package, fully WEEE and RoHS compliant
