描述
the lm5009 step-down switching regulator features all of the functions needed to implement a low-cost, efficient, buck bias regulator. this device is capable of driving a 150-ma load current from a 9.5-v to 95-v input source. the switching frequency can exceed 600 khz, depending on the input and output voltages. the output voltage can be set from 2.5 v to 85 v. this high-voltage regulator contains an n-channel buck switch and an internal startup regulator. the device is easy to implement and is provided in 8-pin vssop and thermally-enhanced, 8-pin wson packages. the lm5009 is a well-suited alternative to a high-voltage monolithic or discrete linear solution where the power loss becomes unacceptable.
