Product Overview

The RT7232GQW is a 4A, 18V, 650KHz, Advanced Constant On-Time (ACOT) synchronous step-down converter in 10 pin WDFN package. It achieves high power density to deliver up to 4A output current from a 4.5V to 18V input supply. The ACOT mode offers an optimal transient response over a wide range of loads and all kinds of ceramic capacitors which allows the device to adopt very low ESR output capacitor for ensuring performance stabilization. In addition RT7232 keeps an excellent constant switching frequency under line and load variation and the integrated synchronous power switches with the ACOT mode operation provides high efficiency in whole output current load range. Cycle by cycle current limit provides an accurate protection by a valley detection of low side MOSFET and external soft-start setting eliminates input current surge during start-up. Protection functions include thermal shutdown, output under voltage protection/ over voltage protection.
  • 50mohm internal low side N-MOSFET
  • Support all ceramic capacitors
  • Up to 95% efficiency
  • Discontinuous operating mode at light load
  • Adjustable output voltage from 0.765V to 8V
  • Adjustable soft start

Applications

Power Management, Industrial, Commercial, Consumer Electronics

Warnings

ESD sensitive device, take proper precaution while handling the device.
