概述
The LP6239 is a high performance non-synchronous boost converter controller that drives N-channel power MOSFETs. Synchronous rectification increases efficiency, reduces power losses and eases thermal requirements, allowing the LP6239 to be used in high power boost applications.A 2.5V to 6V input supply range encompasses a wide range of system architectures. The LP6239 features operating fixed-frequency at 600kHz and a 1.215V reference voltage. The CS pin can adjustable the current limited and slope compensation by permutations the external resistor . Other features include over current protection (OCP), output over voltage protection (OVP), and under-voltage lockout (UVLO). The LP6239 is available in SOP-8 (0.5mm pitch) package.
