The LV5232VH-TLM-H is a powerful PMIC-LED driver offering high current control, slew rate control and a low dropout regulator. This integrated system is ideal for applications where multiple LED channels are powered simultaneously. The LV5232VH-TLM-H provides advanced features such as a low-noise, low-ripple step-down regulator and a wide frequency range (up to 5.0 MHz). An LED driver allows LED current to be controlled accurately and is suitable for driving multiple LED strings in parallel.

The PMIC-LED driver offers an output voltage of up to 12V and is capable of driving up to 15 LEDs simultaneously. It includes multiple current sinks and PWM control, with each channel capable of producing up to 1.25 amps. The device can be configured to provide constant current output for LEDs-based lighting, as well as for low-voltage industrial applications such as LED displays and LED decorations. The LV5232VH-TLM-H also includes a low dropout (LDO) regulator that allows conversion of a higher input voltage (9-14V) down to a 3.3V voltage reference.

The LV5232VH-TLM-H features an advanced thermal design, with a built-in thermal shutdown circuit that can protect the device from over-temperature conditions. It is designed to be used with an external high-side N-channel MOSFET and low-side P-channel MOSFETs. The device has two additional channels capable of generating a 4th order low pass filter, which can be used to filter out unwanted electro-magnetic interference (EMI).

The LV5232VH-TLM-H utilizes a Constant-on-Time (COT) control mechanism for regulating current across LEDs. The device has an adjustable leading-edge blanking timer that prevents false triggering during transient loads. The leading-edge blanking timer can also be used to achieve improved peak light efficiency. The device features both positive and negative over-temperature protection and is designed to operate in temperatures of up to 100°C.

The LV5232VH-TLM-H is a versatile, powerful PMIC-LED driver, capable of powering multiple LEDs simultaneously. This highly integrated system includes a low-dropout regulator, adjustable PWM control and multiple current sinks to drive up to 15 channels. The device is suitable for applications such as LED displays, decorations and industrial lighting. Thanks to its advanced thermal design, it can also be used in high temperature environments.
