The AS3693B-ZTQW is a PMIC – LED driver that is mainly used for providing current to light emitting diodes in both AC and DC applications. The AS3693B-ZTQW is a part of the broader family of AS3693 PMICs – full name being PeakView AS3693 PMICs. It is a cost-effective and high-quality product that has a space-saving design hence it is suitable for both hand-held and industrial applications.

The device is based on the synchronous and monolithic boost topology operating in hysteretic mode. It is also equipped with a high-voltage sense pin and a zero current switching feature to further enhance efficiency. The AS3693B-ZTQW operates from an input voltage range of 2V-6V and is capable of delivering a maximum output current of 1.7A. It is also equipped with Lockure™ advanced substitution technology to provide an improved stability and efficiency. The patented Lockure™ technology makes the device even more reliable and robust when compared with other LED drivers in the same family.

The AS3693B-ZTQW provides both PWM and analog dimming capabilities. PWM dimming works by adjusting duty cycle while analog dimming works by varying input voltage. It supports both boosted and buck modes. Apart from being highly efficient, the driver is also very reliable due to its over current protection (OCP) and over temperature protection (OTP). It also has a programmable soft start and a power good signal, which ensures that the driver starts and remains stable in operation.

The device is packaged using the latest DRG technology, which makes it ideal for use in low-profile applications. It also comes with a low quiescent current of 8µA, decreasing overall system power consumption and cost. This makes it more affordable and cost-effective when compared with other LED drivers.

In summary, the AS3693B-ZTQW is a reliable and cost-effective PMIC – LED driver. It is optimal for both commercial and industrial applications and combines high efficiency, robustness and reliability in one package. It is capable of both analog and PWM dimming and also features Lockure™ advanced substitution technology and a low quiescent current for higher efficiency and maximum cost savings. It is packaged using DRG technology and can be used for both AC and DC applications.
