NCP6914
5 Channel PMIC: 1 DCDC
Converter and 4 LDOs
The NCP6914 integrated circuits are part of the ON Semiconductor
mini power management IC family (PMIC). They are optimized to
supply battery powered portable application sub−systems such as
camera function and microprocessors. These devices integrate 1 high
efficiency 800 mA Step−down DC to DC converter with DVS
(Dynamic Voltage Scaling) and four low−dropout (LDO) voltage
regulators in a WLCSP20 1.77 x 2.06 mm package.
Features
• 1 DCDC Converter (3 MHz, 1 mH/10 mF, 800 mA)
♦ Peak Efficiency 95%
♦ Programmable Output Voltage from 0.6 V to 3.3 V by 12.5 mV
Steps
• 4 Low Noise − Low Dropout Regulators (300 mA)
♦ Programmable Output Voltage from 1.0 V to 3.3 V by 50 mV
Steps
♦ 50 mV_rms Typical Low Output Noise
• Control
♦ 400 kHz / 3.4 MHz I²C Compatible
♦ Hardware Enable Pin
♦ Power Good and Interrupt Output Pin
♦ External Synchronization
♦ Customizable Power Up Sequencer
• Extended Input Voltage Range 2.3 V to 5.5 V
• Optimized Power Efficiency
♦ 72 mA Very Low Quiescent Current at No Load
♦ Less than 1 mA Off Mode Current
• Small Footprint: Package 1.77 x 2.06 mm WLCSP
• These are Pb−Free Devices
Typical Applications
• Cellular Phones
• Digital Cameras
• Personal Digital Assistant and Portable Media Player
• GPS Systems
