概述
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 450KHz 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.
