NIS5102 SMART HotPlug™ is a hot swap protection device for +12 V circuits. The combination of an integrated
power MOSFET switch and a unique temperature-sensing capability makes this the most robust hot swap IC available. This highly integrated device also provides adjustable current limit with no external shunt required, undervoltage and overvoltage lockout, and a power good indicator.
NCP1582 Low Voltage Synchronous Buck Controller is a voltage mode PWM controller designed to operate from
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).
NCP5210 3-In-1 PWM Dual Buck and Linear DDR Power Controller contains two synchronous PWM buck control-
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.
NCP5425 Dual Synchronous Buck Controller is a highly flexible device with internal gate drivers that can provide
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.
