High-Efficiency Synchronous Buck Converter with Wide Input Range and Adjustable Output for Stable Power Supply

The HX1198NLT is a high-performance synchronous buck (step-down) DC-DC converter developed for compact, power-sensitive electronic systems. It efficiently converts a higher input DC voltage to a lower, stable output DC voltage, catering to the power needs of low-voltage components like microchips, sensors, and portable device circuits.

• High-Efficiency Step-Down Conversion: Utilizes synchronous rectification technology to achieve conversion efficiency up to 95% under typical load conditions, minimizing power loss and reducing heat generation.
• Wide Input & Adjustable Output Ranges: Supports a broad input voltage range (commonly 4.5V DC – 36V DC) and allows flexible output voltage adjustment (typically 0.8V DC – 24V DC) via external resistors, adapting to diverse system power requirements.
• High Current Capacity: Delivers a maximum continuous output current of up to 8A (varies by specific model), capable of powering high-current-consuming components like advanced microprocessors or LED arrays.
• Stable Output Regulation: Features tight output voltage regulation (typically ±1.5% tolerance) and fast transient response, ensuring consistent voltage supply even when the load changes rapidly.
• Comprehensive Protection Mechanisms: Integrates multiple safeguards, including over-voltage protection (OVP), over-current protection (OCP), over-temperature protection (OTP), and under-voltage lockout (UVLO), preventing damage to the converter and connected loads.
• Compact & Low-Noise Operation: Adopts a small SMD package (e.g., QFN) for space-saving installation, and supports frequency synchronization (optional) to reduce electromagnetic interference (EMI), suitable for noise-sensitive systems.

• Consumer Electronics: Used in portable devices (e.g., high-power Bluetooth speakers, portable projectors), smart home appliances (e.g., intelligent thermostats, security cameras), and wearable tech, providing efficient power for core control circuits.
• Industrial Electronics: Deployed in industrial sensors, IoT gateways, and small-scale PLCs (Programmable Logic Controllers), leveraging its wide input range to adapt to unstable industrial power supplies.
• Automotive Electronics: Applied in in-vehicle auxiliary systems (e.g., dashboard displays, USB charging ports, vehicle-mounted cameras), withstanding the 12V/24V automotive electrical system voltage fluctuations.
• LED Lighting Systems: Powers high-current LED strips, automotive LED headlights, or industrial LED lamps, ensuring stable current supply for consistent brightness and extended LED lifespan.
• Communication Equipment: Integrated into small network devices (e.g., mini routers, 4G/5G modules) and wireless data terminals, delivering reliable low-voltage power for signal processing units.
