The MAX16834AUP/V+T is a Pulse-Width-Modulation (PWM) current control mechanism power source chip integrated with the TDFN-EP package. It is an application field of the Power Management and Integrated Circuit (PMIC), and it is important part of three-channel LED driver in PMIC. MAX16834AUP/V+T chip utilizes key features such as independent current control for each LED, PWM dimming with up to 1,000:1 dynamic range, and open/short LED protection.The purpose of MAX16834AUP/V+T is to provide a low-cost high performance power supply controller for LED illumination applications. The chip essentially combines two different voltage components into one package. First, it contains a high voltage, low power MOSFET driver and LED current regulator, and second, it consists of a high current MOSFET driver for shared LED current sense and LED current control.The MAX16834AUP/V+T is mainly used in LED applications to provide efficient and cost-effective current control and dimming. It can provide current rates up to 20A peak, a voltage range of 0-60V and an output voltage range of 0-6V. In addition, it has several features, such as very low input current, low-level shutdown control, over-temperature protection, and separate LED current channels with configurable LED current.In terms of working principle, MAX16834AUP/V+T is a high-performance Pulse-Width Modulation (PWM) current control mode power source chip. It uses a pair of external power MOSFETs controlled by the MAX16834AUP/V+T to switch the current and voltage. The two MOSFETs are placed in parallel with one at the higher voltage and the other at the lower voltage. The first MOSFET is responsible for the LED current control and the second for the shared current sense.To control the flow of current, MAX16834AUP/V+T can be set to either linear or PWM mode. In the linear control mode, the input voltage is used to regulate the LED current, up to 20amps maximum, while the PWM mode controls the overall power output of the chip. Additionally, the chip provides protection features, such as over-temperature, over-current, and reverse polarity protection, to ensure safety and reliability.Overall, MAX16834AUP/V+T application field and working principle are important part of three-channel LED driver in Power Management and Integrated Circuits (PMIC). It is an efficient and cost-effective solution for LED applications requiring current control, dimming, and protection features. It provides current up to 20A peak, a voltage range of 0-60V, an output voltage range of 0-6V, and independent current control for each LED. In terms of working principle, it uses a pair of external power MOSFETs controlled by the MAX16834AUP/V+T to switch the current and voltage, and it can be set to either linear or PWM mode.
