NCP1532
:
Dual 2.25 MHz Step-Down DC-DC Converter, Up to 1.6 A
- Supplies core and I/O voltages for portable multimedia applications powered from 1-cell Li-Ion or 3-cell alkaline/NiCd/NiMH batteries
- Both channels are externally adjustable from 0.9 to 3.3 V and can source a total of 1.6 A, 1.0 A maximum per channel
- 2.25 MHz switching frequency cuts component size by allowing a small inductor (down to 1.0 uH) and capacitors; operates 180 degrees out-of-phase to minimize current demand on the battery
NCP1338
:
Enhanced Current-Mode Controller for Free Running Quasi-Resonant Operation
- QR operation ensures full borderline/critical conduction mode in any line/load condition
- Influence of the input voltage over the maximum output power is compensated
- Soft-Skip™ mode is initiated when power demand falls below a predetermined level
NCP3120
NCP3121
NCP3122
NCP3123
:
Dual 2.0 and 3.0 A Integrated Switching Regulators with Sequencing
- Auto-tracking and sequencing to meet critical timing and sequencing requirements without additional circuitry
- Externally adjustable switching frequency from 200-750 kHz in the NCP3120/NCP3121, and 1000-2200 kHz in the NCP3122/NCP3123; switching 180° out-of-phase for reduced input capacitance requirement
- Input voltage for +5.0 V and +12 V designs; output voltage as low as 0.8 V; QFN-32 package

NTHD2110T
:
-12 V P-Channel Power MOSFET with Integrated TVS
- Leading edge trench technology yields low RDS(on) and improved system efficiency
- Integrated TVS provides a robust 15 kV contact discharge ESD protection for system reliability
- 1.8 V gate rating for low voltage logic compatibility; space saving 3.0 x 1.9 mm ChipFET™ package
NUD4700
:
LED Shunt
- Provides a current bypass in the case of one LED in a series string going into open circuit
- Ensures system reliability, especially for systems where safety or inaccessibility are imperative, such as headlights, lighthouses, bridges, aircraft, runways
- Use with 1.0 W LEDs (nominally 350 mA at 3.0 V) or other loads where circuit continuity is required
