High Efficiency 2.6A Boost DC/DC Convertor



General Description

The LP6238 is a current mode boost DC-DC converter. Its PWM circuitry with built-in 2.6A current power MOSFET makes this converter highly power efficiently. The LP6238 implements a constant frequency 1MHz PWM control scheme. The high frequency PWM operation also saves board space by reducing external component sizes. The LP6238 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 LP6238 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The LP6238 is available in a small 6-pin SOT23-6 package.
