NCP1582, NCP1582A,

NCP1583

Low Voltage Synchronous

Buck Controllers

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 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.
