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.
