NCP81149
Single-Phase Voltage
Regulator with SVID
Interface for Computing
Applications
High Switching Frequency, High
Efficiency, Integrated Power MOSFETs
The NCP81149, a single−phase synchronous buck regulator,
integrates power MOSFETs to provide a high−efficiency and
compact−footprint power management solution for new generation
computing CPUs. The device is able to deliver up to 14 A TDC output
current on an adjustable output with SVID interface. Operating in high
switching frequency up to 1.2 MHz allows employing small size
inductors and capacitors while maintaining high efficiency due to
integrated solution with high performance power MOSFETs.
Current−mode RPM control with feedforward from both input power
supply and output voltage ensures stable operation over wide
operation condition. The NCP81149 is in a QFN48 6 x 6 mm package.

Logic Input
Description
Voltage Supply of Controller. Power supply input pin of control circuits. A 1 mF or larger
ceramic capacitor bypasses this input to ground. This capacitor should be placed as close
as possible to this pin.
Enable. Logic high enables the device and logic low makes the device in standby mode.

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
1. Latch up Current per JEDEC standard: JESD78 class II.
2. The thermal resistance values are dependent of the internal losses split between devices and the PCB heat dissipation. This data is based
on a typical operation condition with a 4−layer FR−4 PCB board, which has two, 1−ounce copper internal power and ground planes and
2−ounce copper traces on top and bottom layers with approximately 80% copper coverage. No airflow and no heat sink applied (reference
EIA/JEDEC 51.7). It also does not account for other heat sources that may be present on the PCB next to the device in question (such as
inductors, resistors etc.)
3. The maximum power dissipation (PD) is dependent on input voltage, output voltage, output current, external components selected, and PCB
layout. The reference data is obtained based on TJMAX = 125°C and RθJA = 21.8°C/W.
4. Moisture Sensitivity Level (MSL): 1 per IPC/JEDEC standard: J−STD−020A.
