Modifications

• In Section 2, added up to 15 A load capability for Buck Controller - External FET

• In Figure 1, under SW@ - Buck Controller, changed >10 A to up to 15 A

• In Section 10, added this note below the table: In the absence of BIAS_IN, VIN falling below this

voltage will cause FS5600 to power off

• In Section 12.1, corrected the units of Error Amplifier Transconductance from ms to mS

• In Section 12.2.1, added this to the end of the paragraph after the first table: When operating at 450

kHz or lower, by choosing low Rds(on) MOSFETs in separate packages, and with a low DCR inductor,

SW2 can be designed to support loads of up to 15 A. Refer to the schematic of KITFS5600FRDMEVM

for a design that can support 15 A.

• Reorganized Section 12, adding Section 12.2.1.2 material

• In Section 12.2.1.1, added Use closest standard values for resistor and capacitors to the end of the

section

• In Section 17.6.1, added PGOODx toggle due to a before watchdog failure

• In Section 17.13.7, changed OTP_DFN_EN to OTP_DFS_EN

• Added Section 19

• In Figure 11, in the Divider 1 box, changed /8 to /7. In the Divider 2 box, changed /48 to /44.

• In Figure 33, made these pin numbering changes at the lower left:
