Introduction
The RT7231/32/33/34 is a synchronous step-down DC/ DC converter with Advanced Constant On-Time (ACOT) mode control. It achieves high power density to deliver up to 4A output current from a 4.5V to 18V input supply. The proprietary 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, RT7231/32/33/34 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 startup. Protection functions include thermal shutdown for RT7231/32/33/34, output Under Voltage Protection (UVP) / Over Voltage Protection (OVP) for RT7231/32. When the UVP/OVP is triggered, the device will enter latch mode for TSSOP-14 (Exposed Pad), and hiccup mode for WDFN-10L 3x3. The RT7231/32 are available in TSSOP-14 (Exposed Pad) and WDFN-10L 3x3 packages, and the RT7231 is operated in forced continuous conduction mode. The RT7233/34 are available in the SOP-8 (Exposed Pad) package, and the RT7233 is operated in forced continuous conduction mode.
