1 / 7 page  LP6212A-01 Jan.-2017 Email: marketing@lowpowersemi.com www.lowpowersemi.com Page 1 of 7 Preliminary Datasheet LP6212A High Efficiency 4A Boost DC/DC Convertor General Description The LP6212A is a current mode boost DC-DC converter. Its PWM circuitry with built-in 4A Current power MOSFET makes this converter highly efficient. The LP6212A implements a constant frequency 1MHz PWM control scheme. The high frequency PWM operation also saves board space by reducing external component sizes. The LP6212A features automatic shifting to pulse frequency modulation mode at light loads.Highly integration and internal compensation network minimizes as 6 external component counts. Optimized operation frequency can meet the requirement of small LC filters value and low operation current with high efficiency. The LP6212A includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The LP6212A is available in a small SOT23-6 package.
