Product Preview 2.5 A Boost Regulator with Bypass Function The NCP6868 is a synchronous boost converter. It is designed primarily to boost new generation low-voltage Li-Ion batteries (silicon anode-like) embedded into cell and smart phones. The objective is to guarantee a minimum output voltage even in the case for which the battery voltage is below the minimum voltage required by the system. The device features a Bypass mode coupled with a Boost mode. It is capable to drive a continuous load up to 2.5 A and it operates at a switching frequency of 2.5 MHz. An I2C serial control can also be enabled for configuring the output voltage and peak current limit. The NCP6868 is available in a space saving, low profile 1.8 × 1.8 mm CSP-16 package. Features • 2.35 V to 5.5 V Input Voltage • Fixed or Programmable VOUT: from 2.85 V Up to 5.3 V • Bypass Operation when VIN is Above or Close to VOUT • Few External Components & 0.47 H Inductor • High Efficiency Up to 98% • Output Current Up to 2.5 A Continuous (VIN = 2.6 V, VOUT = 3.5 V) and up to 4 A Peak Current • Inductor Peak Current up to 9.0 A • Forced Bypass Option through BP Pin • Low Quiescent Current: 50 A • Voltage Control Pin (VSEL) to Precisely Adjust VOUT • I2C Serial Control as a Software-Mode Option to Program Output Voltage and Peak Current Limit • Soft-Start Function (SS) to Limit Inrush Current • Current Limitation to Protect Against Short Circuit • Thermal Limit Protection • Small 1.8 × 1.8 mm / 0.4 mm Pitch CSP Package • These Devices are Pb−Free and are RoHS Compliant T

Typical Applications • Boost Converters for New Generation Low-Voltage Li-Ion Batteries • USB OTG (On-The-Go) • 3G/4G – LTE RF PA • Cell Phones, Smart Phones, Phablets, Tablets & Webtablets
