power MOSFET switch and a unique temperature-sensing capability makes this the most robust hot swap IC avail-

able. This highly integrated device also provides adjustable current limit with no external shunt required, undervolt-

age and overvoltage lockout, and a power good indicator.

a 5 V or 12 V supply and produce an output voltage as low as 0.8 V. Features include a 0.7 A gate driver and an

internally set 350 kHz oscillator. The NCP1582 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).

ler for driving four external N−Ch FETs to form the DDR memory supply voltage (VDDQ) and the MCH regulator.

Protective features include, soft−start circuitry, undervoltage monitoring of 5VDUAL and BOOT voltage, and thermal

shutdown.

two independent outputs or one high current output. This feature-rich controller offers adjustable switching

frequency up to 750 kHz and a ±1% 0.8 V reference.
