This datasheet also covers the NCP1582 variant, as both devices belong to the same low voltage synchronous buck controller family and are provided as variant models within a single manufacturer datasheet.
General Description
Pin No.
1 BST Supply rail for the floating top gate driver.
To form a boost circuit, use an external diode to bring the desired input voltage to this pin (cathode connected to BST pin).
Key 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.

ntroller 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. Features •
