The device contains six step-down – Cores Bundled to a 6-Phase Converter DC/DC converter cores, which are bundled together in a 6-phase buck converter. The device is fully – Load Current Reporting controlled by a Dynamic Voltage Scaling (DVS) – Programmable Overcurrent Protection (OCP) interface or an I2C-compatible serial interface. – Auto PWM/PFM and Forced-PWM Operations The automatic PWM/PFM operation together with the and Automatic Low Power-Mode Setting automatic phase adding/shedding maximizes – Automatic Phase Adding/Shedding efficiency over a wide output current range. The LP8754 supports remote differential voltage sensing – Remote Differential Feedback Voltage Sensing to compensate IR drop between the regulator output – Output Voltage Ramp Control and the point-of-load thus improving the accuracy of – VOUT Range = 0.6 V to 1.67 V the output voltage. • I2C-Compatible Interface which Supports Standard The protection features include short-circuit (100 kHz), Fast (400 kHz), and High-Speed (3.4 protection, current limits, input OVP, UVLO, MHz) Modes temperature warning, and shutdown functions. • Four Selectable I2C Addresses Several error flags are provided for status information of the IC. In addition, I2C read-back includes total • Interrupt Function with Programmable Masking load current and load current for each buck core: The • Output Short-Circuit and Input Overvoltage LP8754 has the ability to sense current being Protection (OVP) delivered to the load without the addition of current • Spread Spectrum and Phase Control for EMI sense resistors. During start-up, the device controls Reduction the output voltage slew rate to minimize overshoot and the inrush current. • Overtemperature Protection (OTP) • Undervoltage Lock-out (UVLO) Device Information(1) PART NUMBER PACKAGE BODY SIZE (MAX) 2 Applications LP8754 DSBGA (49) 3.022 mm x 2.882 mm • Smart Phones, eBooks and Tablets (1) For all available packages, see the orderable addendum at • GSM, GPRS, EDGE, LTE, CDMA and WCDMA the end of the datasheet.
