Description

DAP005 is Advanced transition-mode PFC controller. The device is a current-mode PFC controller operating in Transition Mode (TM). Based on the core of a standard TM PFC controller, it offers improved performance and additional functions.

The highly linear multiplier, along with a special correction circuit that reduces crossover
distortion of the mains current, allows wide-range-mains operation with an extremely low
THD even over a large load range.

A Transition-Mode Power Factor Correction (PFC) controller is a specialized electronic circuit or component used in power supplies and converters to improve power factor and increase the overall efficiency of the power conversion process. Power factor correction is important because it helps reduce the amount of reactive power in an electrical system, which can lead to more efficient energy usage and reduced electricity costs.

Features

1. Transition-mode control of PFC pre-regulators

2. Very precise adjustable output overvoltage protection

3. Tracking boost function

4. Protection against feedback loop failure (Latched shutdown)

5. Interface for cascaded converter’s PWM controller

6. Input voltage feedforward (1/V2)

7. AC brownout protection

Pinouts:

Applications:

1. PFC pre-regulators for:

(1) HI-END AC-DC adapter/charger

(2) Desktop PC, server, WEB serve

A capacitive touchscreen controller is an integrated circuit (IC) that is responsible for detecting and processing touch inputs on a capacitive touchscreen panel. Capacitive touchscreens are widely used in smartphones, tablets, laptops, interactive kiosks, and various other electronic devices due to their responsiveness, durability, and multi-touch capabilities. The controller plays a crucial role in accurately sensing touch gestures and translating them into digital signals that the device’s operating system can understand and respond to.
