Description

The AU6989 USB 2.0 Flash Disk Controller is the best high performance solutions for SLC (Single- Level Cell), MLC (Multi-Level Cell) NAND and AG-AND with multiple dies data flash. Its high-speed read (30MB/Sec) and write access performance enable users to transfer and backup data effectively. Besides, AU6989 is certified by USB-IF (USB Implementers Forum), WHQL (Window Hardware Quality Labs) and EMI tests to guarantee the quality and reliability for end-users.

With multiple functions integrated into one chip and external components built inside, AU6989 is pledged to deliver the best performance benchmark and to further reduce the BOM cost of end products adopting this solution. It provides dual channel access and ISP (In-System Programming) technologies, which are the most important features to allow manufacturers building high performance UFD easily and to have the flexibility of adopting different source of flash chips.

Similar features and reference parts

A dual-output PWM (Pulse Width Modulation) controller is an integrated circuit designed to generate two separate PWM signals simultaneously. PWM is a technique used to control the average value of a signal by varying the duty cycle of a square wave. It’s commonly used in applications like power supplies, motor control, lighting control, and more.

Description

The RT8880A is a 3 + 2 phases PWM controller, and is compliant with AMD SVI2 Voltage Regulator Specification to support both CPU core (VDD) and Northbridge portion of the CPU (VDDNB). The RT8880A features CCRCOT (Constant Current Ripple Constant On-Time) with G-NAVP (Green-Native AVP), which is Richtek’s proprietary topology. The G-NAVP makes it an easy setting controller to meet all AMDAVP (Adaptive Voltage Positioning) VDD/ VDDNB requirements. The droop is easily programmed by setting the DC gain of the error amplifier.
