SKY87020-12 Functional Block Diagram Functional Description The SKY87020-12 has three main functional blocks, a DC-DC boost converter, a 4.5 V charge pump boost converter and a nonregulating charge pump voltage divider. The operation of each block is conditional on the applied input supply voltage (VIN) and the controlling reference input signal level (VREF). There are output operating voltage states that can be set by the applied VREF signal that cannot be supported by either the DC-DC boost or divide-by-2 charge pump. In these cases, the device output will default to bypass the input supply from VIN to OUT. The theory of the device and system operation is to always supply the requested voltage or greater to the load circuit (SkyBlue™ PA). To support 2G PA operation, the SKY87020-12can supply a 3.2 V bias supply when the system supply voltage drops to or below 3.2 V. DC-DC Boost Converter Section DC-DC boost converter can supply a boost output voltage from 2.5 V to 11.0 V from a 2.5 V to 5.5V input supply range and supports load current levels up to 300 mA. Step-Up power conversion is achieved through a multimode PFM/PWM control architecture to achieve the maximum possible boost mode efficiency over the varied input and output voltage and load current conditions. The high 1.8 MHz switching frequency operation permits fast transient response and is capable of wide duty cycle ranges up to 90%. The switching frequency is reduced to 1.4 MHz (typical) when VOUT is set to levels below 7 V to save IC operating quiescent current at low output voltage/light load conditions to improve power conversion efficiency. To simplify the operation and use, the switching regulator is internally compensated to eliminate the need for additional external compensation network components. The high switching frequency is optimized to reduce external components sizes and values (1.5 μH inductor typical with 4.7 uF input/1.0 uF output capacitors) for space constrained applications. Upon IC enable, the output capacitor will be charged to the level of VIN in less than 60 μs to aid in fast output voltage step response timing. The Boost converter has a quick-start circuit to support fast voltage step response at IC start-up and at any time the applied VREF signal causes the boost output step-up to increase by 1V or more. To achieve <20 μs voltage step timing with a 1.0 μF output capacitor, the boost quick-start circuit allows peak inductor current to flow at the over current limit threshold (2.5 A typical, 2.7 A maximum) level for several switch mode clock cycles to speed charging of the output capacitor. For this reason an inductor must be used with a saturation current rating equal to or greater than the specified over current protection threshold level (2.7 A maximum).

The IC pinout and external component placement has been arranged so the power flow is from left to right on the layout and all RF PA interconnections can be made from the right side on the IC on the top layer The input capacitor C5 and output capacitor C7 should be connected to the system ground plane common with the RF PA system grounding Ferrite beads may also be added in series with the VBATT supply input, output (OUT) and bias supply output (4V5 output) to further reduce high frequency noise into and out of this power supply circuit. All external components should be placed as close as possible to the IC pin connections. Power ground must be placed on a bottom, middle layer, or power ground layer on a multi-layer PCB Layout. It is preferable to have the power ground plane/layer on the mid/inner layer 1 right below the top layer. Figure 13 shows the recommended PCB layout with components. The IC PGND, 4V5 capacitor (C4), input capacitor (C6), and output capacitor (C2) should all be connected to a power ground island with as many interconnecting vias as possible to achieve the lowest connection impedance between the circuit nodes.
