The CAT3612HV2-GT2 PMIC - LED Driver is a cut-down, low-voltage, step-down regulator ideal for many low-voltage applications. This device has a two-stage switch design that provides both high accuracy and high efficiency. The CAT3612HV2-GT2 PMIC - LED Driver is an excellent choice for applications such as High Reliability Lighting, IP Pockets and LCD Displays.

The CAT3612HV2-GT2 PMIC - LED Driver’s working principle consists of two stages. The first stage consists of a linear regulator and pre-regulator architecture known as the Peak Current Amplification Mode™ (PCAM™). In PCAM, the linear regulator continuously monitors the output charged current and builds a sample-hold capacitor to regulate the output voltage.

The second stage is an active peak-current limiting circuit that constantly monitors the output current and calculates the current density. When the LED current density reaches the threshold level, the unit will stop charging the LED. This feature prevents LEDs from being damaged due to excessive current or thermal overload.

The device’s features and benefits include a high efficiency of up to 95%, low power consumption, a wide input voltage range, and a fast output start-up time. Additionally, the CAT3612HV2-GT2 PMIC - LED Driver comes with Smart Highside Output and Auto-Start Functionality that makes it simple to use and configure.

The CAT3612HV2-GT2 application field is mostly focused on energy-efficient LED lighting designs that require high efficiency and low standby power. The driver is used in a wide variety of applications including industrial luminaires, strip lighting, office lighting, down lighting, and many more. It can also be used to power up outdoor installations, for example in street lighting or tunnel lighting projects.

In terms of output performance, the CAT3612HV2-GT2 driver delivers a high efficiency of up to 95%, low standby power and a fast startup time. What’s more, the linear-regulator architecture provides superior power supply accuracy, ensuring LEDs are accurately driven and brightness is maintained.

In conclusion, the CAT3612HV2-GT2 PMIC - LED Driver is an ideal low-voltage step-down regulator for both high-reliability lighting and IP pocket applications. It combines a PCAM-based linear regulator and an active peak-current limiting circuit to deliver high efficiency, low power consumption, wide input voltage range and a fast output start-up time. Ultimately, the device offers the user an easy way to ensure the LEDs are efficiently powered and brightness is maintained.
