RT3624QEGQW Integrated Circuit Chip Dual Channel PWM Controller For IMVP9.1 CPU Core Power Supply

RT3624QEGQW is a synchronous buck controller which supports 2 output rails and can fully meet Intel IMVP9.1 requirements. The RT3624QEGQW adopts G-NAVPTM (Green Native AVP) which is Richtek′s proprietary topology derived from finite DC gain of EA amplifier with current mode control, making it easy to set the droop to meet all Intel CPU requirements of AVP (Adaptive Voltage Positioning).

Based on the G-NAVPTM topology, the RT3624QEGQW features a new generation of quick response mechanism (Adaptive Quick Response, AQR) to optimize AVP performance during load transient and reduce output capacitors. The RT3624QEGQW integrates a high accuracy ADC for platform and function settings, such as ICCMAX, switching frequency or AQR trigger level. The RT3624QEGQW provides VR Ready and thermal indicators. It also features complete fault protection functions including over-voltage (OV), under-voltage (UV), over-current (OC) and under-voltage lockout (UVLO).
