Description
The LP6221A is a current mode boost DC-DC
converter. Its PWM circuitry with built-in 10A
current power MOSFET makes this converter
highly power efficiently. The LP6221A
implements a constant frequency 500KHz
PWM control scheme. The LP6221A can drive
up to 20V output voltage
The LP6221A includes under-voltage lockout,
current limiting, and thermal overload protection
to prevent damage in the event of an output
overload. The LP6221A is available in ESOP-8
/ DFN-10 package.
