The LM5009 from Texas Instruments is a versatile step-down (buck) switching regulator. It is capable of handling a wide input voltage range from 9.5 V to 95 V, making it suitable for various power systems.
This regulator features an integrated N-channel MOSFET and can deliver up to 150 mA of output current. The switching frequency can exceed 600 kHz, allowing for compact external component selection and efficient operation. The output voltage can be set between 2.5 V and 85 V.
Key features include ultra-fast transient response, no loop compensation required, and constant operating frequency due to V IN feedforward. It also incorporates intelligent current limit protection, external shutdown control, and thermal shutdown for robust operation.
The LM5009 is available in two package options: an 8-pin VSSOP measuring 3.00 mm x 3.00 mm and a thermally enhanced 8-pin WSON measuring 4.00 mm x 4.00 mm. These packages facilitate integration into space-constrained designs.
