10.3.3
BOOST5 - STARTUP AND SOFT START
There is a direct path from VIN through the external inductor (L) into the BOOST5_SWn pins, through SR1 to the
BOOST5_OUT pin which directly charges the output capacitor (COUT) to ~VIN. During startup the converter continues
charging to the programmed Output Voltage using Soft Start. During the Soft Start sequence the BOOST5 limits the peak
inductor current for the first 500 s.
The Voltage value in the Output Voltage Register may be changed during the Soft Start sequence.
10.3.4
BOOST5 - PEAK CURRENT LIMITING
During normal operation the BOOST5 converter provides Cycle by Cycle current limiting. If the output voltage drops
10.4 OUTPUT DIODE
Use a schottky diode such as an MSS1P5-E3/89A or equivalent if the converter output voltage is 4.5V or greater. The
schottky diode carries the output current for the time it takes for the synchronous rectifier to turn on. Do not use ordinary
rectifier diodes, since the slow recovery times will compromise efficiency. A schottky diode is optional for output voltages
below 4.5V.
10.5 BOOST5 - APPLICATIONS INFORMATION
VIN (3.0 to 4.5V) typically comes from VSYS
The approximation output current capability versus VIN value is given in the equation below.
IOUT = η x [ILOUT-PEAK – VIN x D / ( 2 x L x f ) ] x ( 1 - D )
Where:
η = estimated efficiency
ILOUT-PEAK = peak current limit value (1.5A)
VIN = Input voltage
D = steady-state duty ratio = (VOUT - VIN )/ VOUT
f = switching frequency (1.0MHz typical)
L = inductance value (2.2uH)
BOOST5 provides 4.05 to 5.0V to the CLASS_D Audio Power Bridge and (optionally) LDOs requiring 5V input.

– BOOST5 Applications Diagram
This block DOES NOT PROVIDE full short circuit protection. When the output voltage drops below the input voltage
there is a direct path through the inductor and internal synchronous rectifier (SR1) directly to the output capacitor.
The BOOST5 power supply block is designed to provide power to the CLASS_D Audio Amplifier and LDOs requiring
input voltage greater than the system voltage. External devices powered by this IP block are expected to provide
their own short circuit protection.
