Low Voltage Synchronous
Buck Controllers
The NCP158x is a low cost PWM controller designed to operate from
158x
ALYW
G
a 5 V or 12 V supply. This device is capable of producing an output
voltage as low as 0.8 V. This 8 ? pin 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 soft ? start function. Protection features include short
circuit protection (SCP) and under voltage lockout (UVLO). The
NCP158x comes in an 8 ? pin SOIC package.
