FEATURES
include a 0.7 A gate driver and an internally set 350 kHz (NCP1582, NCP1582A) and a 300 kHz (NCP1583) oscillator. The NCP158x also incorporates an externally compensated transconductance error amplifier and a programmable soft−start function. Protection features include short circuit protection (SCP) and under voltage lockout (UVLO). The NCP158x comes in an 8−pin SOIC package.FEATURES
