SKY87006数据手册集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF

描述 Description

The SKY87006 is a dynamic output controlled DC-DC step-downconverter for multimode 2G GSM/EDGE, 3G WCDMA, and 4G LTERF Power Amplifier (RFPA) applications. The SKY87006 has aprogrammable output voltage range between 0.4 V and 3.6 V withoptimized efficiency for all operating states where load currentsare 850 mA or less, but can support typical peak load currents upto 1.5 A.

The SKY87006 output voltage is set by using a Mobile IndustryProcessor Interface (MIPI) RF Front-End (RFFE) control with a fastwrite7-bit resolution (30 mV steps) data register or an 8-bit highresolution (15 mV steps) data register.

To cover peak load current demands and low input voltage dropoutconditions, the DC-DC regulation control has an automaticlinear regulator bypass switch to connect from the the sourcebattery supply to the output. This minimizes voltage drop andprovides a 1.5 A (typical) current limit for circuit protection. Theoutput current capability of the DC-DC switching regulator andregulated LDO bypass can support typical load currents up to3.0 A.

High switching frequency operation permits the use of a smallinductor and reduces output capacitance requirements. Reducedexternal component values aid ultrafast transient response needsof cellular RF power amplifier applications. The SKY87006 has alight load power saving mode. Locked PWM operation is madepossible by a MIPI RFFE control register bit. Locking PWMoperation can improve load transient response, which canimprove performance for 2G operating modes.

The SKY87006 is available in a small Wafer Level Chip ScalePackage (WLCSP), and is rated over a range of -40 to +85 °C.
