LX1752CLQ is a high performance step-down power supply controller with wide range of output voltage and load range; it provides flexible power control solutions for electronic systems. It is the most popular product of Power Management & Integrated Circuits (PMIC), Voltage Regulators and DC DC Switching Controllers.

This product is designed to provide a much reduced footprint and a higher efficiency switching ratio than other products. It is also designed to provide high efficiency, low noise output with minimal switching losses. Its features also include robust EMI control and advanced protection features like short/over-voltage, open loop, over-current, and thermal shutdown protection. It is the best choice of the integrated switching regulators for Telecommunication, Industrial, Automotive systems.

The LX1752CLQ operates off a widely adjustable input voltage range from 5V to 24V, and provides up to 23V of output, eliminating the need for extra regulators or transformers. The switching frequency is programmable, from 250kHz to 1.2MHz, allowing for better efficiency over a wide voltage and temperature range. With the built-in oscillator for cycle-by-cycle current limiting and under-voltage lockout protection, the system is efficient enough to boast very low quiescent current.

The LX1752CLQ integrated multiple stages including a low voltage differential amplifier (LVD), buck-boost pre-regulation circuit, a control loop block, Slope compensation and synchronization circuitry. The core of the controller is a pulse width modulated (PWM) control section, and it has an RSSI function that can provide reference voltage, over-temperature protection and an over-current sense. The LVD will detect the voltage or current feedback signal, and then generate the frequency, duty cycle and output power control.

Thanks to the high integration and packaging efficiency, the LX1752CLQ reduces the number of external components, making it the ideal choice for complicated Switching Power Supply Design. It is perfect for high-efficiency Step-Down applications, including telecom servers, battery-powered automotive systems, and industrial automation.

The LX1752CLQ features numerous benefits and versatility. Its main features include high efficiency, low-noise and low power consumption, as well as high integration and packaging efficiency. Its output voltage is adjustable and programmable, and it has a low voltage differential amplifier and a buck-boost pre-regulation circuit. Its wide input voltage range is 5V to 24V and it has an RSSI (RSSI function) and a Pulse width modulation (PWM) control section.

It is the ideal choice for complicated Switching Power Supply Design, due to its high efficiency, low noise, and low power consumption. The LX1752CLQ offers a wide range of output voltage and load range, which allows for more efficient and flexible power control solutions for electronic systems, as well as robust EMI control and advanced protection features like short/overload voltage protection, open loop, over-current, and thermal shutdown.
