Product Overview
The LM5009MM/NOPB is a constant on-time non-synchronous Buck Regulator features all of the functions needed to implement an efficient, buck bias regulator. This device is capable of driving a 150mA load current from a 9.5 to 95V input source. The switching frequency can exceed 600kHz, depending on the input and output voltages. The output voltage can be set from 2.5 to 85V. This high-voltage regulator contains an N-channel buck switch and an internal startup regulator. The LM5009 is a well-suited alternative to a high-voltage monolithic or discrete linear solution where the power loss becomes unacceptable. The regulator operation is based on a control scheme using an ON-time inversely proportional to VIN. This feature allows the operating frequency to remain relatively constant overload and input voltage variations. The control scheme requires no loop compensation, resulting in an ultrafast transient response.
- Integrated N-channel MOSFET
- Ultrafast transient response
- No loop compensation required
- VIN feed-forward provides constant operating frequency
- Highly efficient operation
- Internal startup regulator
- Intelligent current limit protection
- External shutdown control
- Thermal shutdown
- 2.5V Feedback voltage reference with 2% accuracy
- Green product and no Sb/Br
Applications
Power Management, Automotive
