RT7234GSP 产品详情

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.
