The NCP158x is a low cost PWM controller designed to operate from
a 5 V or 12 V supply. This device is capable of producing an output
voltage as low as 0.8 V. This 8pin device provides an optimal level of
integration to reduce size and cost of the power supply. 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 softstart function. Protection features include short
circuit protection (SCP) and under voltage lockout (UVLO). The
NCP158x comes in an 8pin SOIC package.
