LM5009SDC/NOPB DC-DC Buck Converter IC 2.5V 1 Output 150mA
The LM5009SDC/NOPB, manufactured by TI, is a wide-input-voltage (9.5 V to 95 V) non-synchronous buck converter designed for high-efficiency power regulation in industrial and automotive applications. It delivers a fixed or adjustable output voltage (2.5 V to 85 V) with a maximum load current of 150 mA, making it ideal for low-power systems requiring robust voltage conversion. The converter operates at a switching frequency of up to 600 kHz, enabling compact component sizing and fast transient response. Key features include thermal shutdown, undervoltage lockout (UVLO), and overcurrent protection, enhancing safety in fault conditions. The LM5009SDC/NOPB is widely used in battery-powered devices, industrial sensors, and automotive subsystems where space efficiency and durability are critical.
LM5009SDC/NOPB voltage DC-DC converter Key Features
The LM5009SDC/NOPB integrates a high-voltage N-channel MOSFET and a constant on-time (COT) control scheme, ensuring stable operation across varying input voltages and loads. Its input voltage range (9.5 V–95 V) accommodates unregulated power sources, while the output voltage (2.5 V–85 V) supports diverse system requirements. The converter achieves up to 93% efficiency under typical loads, minimizing power loss and heat generation. It features soft-start circuitry to reduce inrush current during startup and intelligent current limiting to prevent damage during short circuits. The 8-pin WSON package includes an exposed thermal pad for improved heat dissipation, and its RoHS-compliant, lead-free design meets environmental standards. Additional specifications include 485 μA quiesient current, 1 μA shutdown current, and 600 kHz maximum switching frequency, balancing performance and power consumption.
