IC revision1.00

Description

The RAA211233 is an integrated 24V, 3A, 1.4MHz synchronous buck regulator with current mode constant on-time (COT) control. The RAA211233 features comprehensive protection including input undervoltage lockout (UVLO), overcurrent protection (OCP), output undervoltage protection (OUVP), and over temperature protection (OTP).

Features

  • 4.5V to 24V input supply range
  • Up to 3A output current
  • Integrated high-side (85mΩ) and low-side (45mΩ) MOSFETs
  • 1.4MHz switching frequency
  • 400μA quiescent current
  • Minimum on-time of 66ns
  • Minimum off time of 250ns
  • 0.6V reference voltage with 2% accuracy
  • PFM mode under light-load condition
  • Current mode Constant On-Time (COT) control with internal compensation
  • Internal 1.2ms soft-start time
  • Protection: Low-Side Overcurrent (LSOC) limit, input Undervoltage Lockout (UVLO), Over-Temperature Protection (OTP), Output Undervoltage Protection (OUVP) with Hiccup Mode
  • Accurate EN threshold
  • 6 LD TSOT23 package

Typical applications

  • Embedded systems and I/O supplies
  • Industrial power supplies
