TL7660CDGKR is a unique DC/DC switching regulator manufactured by Texas Instruments. This is a low-noise, ultra-low-dropout, low-power, wide-output-voltage-range controller designed to drive buck, boost and buck/boost applications. This device can drive loads up to 500mA, which makes it suitable for many applications. It provides adjustable output currents, making it ideal for general-purpose step-down applications.

TL7660CDGKR belongs to PMIC – Voltage Regulators – DC DC Switching Regulators family. It has been designed with several features that make it ideal for its application field. Some of the features of this device includes the following.

• It is a high-performance, high-efficient DC-to-DC LED driver which can achieve 4A peak output current.
• It has low dropout voltage for lower noise and improved efficiency.
• It offers wide output voltage range from 0.8V to 12V.
• It has a 50MHz PWM switching frequency for flexibility in design.
• It also supports green-mode for power-saving applications.

How TL7660CDGKR works? It consists of two separate circuits - an inverting buck-boost voltage regulator to generate and control the output voltage, and a low-noise, high-efficiency pulse-width-modulation (PWM) controller. The input voltage is regulated and controlled by the inverter buck-boost circuit. The PWM controller is used to generate switching pulses to control the output voltage. In order to ensure stability, the PWM controller has built-in voltage loop compensation circuitry.

TL7660CDGKR is ideal for powering applications such as digital signage, DVD players, LCD monitors, point-of-sale (POS) systems, medical devices, and portable electronics. It is suitable for step-down application in a wide output range from 0.8V to 12V. It is also adapted for green-mode applications. The wide voltage range, low noise, and low power requirements make this device suitable for many applications.

Overall, the TL7660CDGKR is an excellent choice for low-noise, low-power, high-efficiency DC-to-DC LED driver in an ultra-low-dropout application. It can boost, buck, and buck/boost applications and is capable of driving loads up to 500mA. With its adjustable output current, this device is perfect for general-purpose step-down applications.
