Microsemi . C OM The LX1736 operates as a Current Mode PWM Buck regulator that switches to PFM mode under light loads. The entire regulator function is implemented with only a few, lowcost external components. The LX1736 responds quickly to dynamic load changes using a high bandwidth error amplifier and internal compensation.
