RT2702 - Step-Down DC-DC Controller

Description

The RT2702 is a high-efficiency and high-current synchronous buck controller and is compatible with a DrMOS module.

RT2702 is a highly integrated chip which merges with COT (Constant-On-Time) PWM controller and PWM signal for DrMOS.

Features

  • two kinds of mode transition functions in light load condition, audio skipping mode (ASM) for better light load efficiency and forcedCCM mode (FCCM) for better load transient performance. For the current sensing.

Sample & Buy ® RT2702 Step-Down DC-DC Controller with Remote Sense General Description The RT2702 is a high-efficiency and high-current synchronous buck controller and is compatible with a DrMOS module. RT2702 is a highly integrated chip which merges with COT (Constant-On-Time) PWM controller and PWM signal for DrMOS. Hence, the external circuits for RT2702 are not only easy to design, but component count can be saved as well. For the control topology, the RT2702 adopts FCOT that responds instantly to input voltage change. Besides, the RT2702 includes a 5V (VDRV) linear regulator which can provide 5V voltage and supply up to 100mA for DrMOS.
