1 Hardware Configuration

The TSW2200EVM (Figure 1) provides users with a multiple-output power supply board using a switching

regulator and low-dropout (LDO) regulators. With an onboard TUSB3210 integrated circuit (IC) and

UCD90120A sequencer, users can configure the EVM to operate in either manual or sequencer mode.

Manual operation allows each output to be turned on or off with a jumper setting, whereas the sequencer

operation allows precise configurability of turnon time using the Fusion GUI software.

1.1 Input Power Source

The input supply for the TSW2200 can be a voltage of 10 V to 20 V using banana jacks, a 19-V Dell™

laptop charger, or a 12 V @ 2 A (AC-to-DC) power module. These input voltages are stepped down to 6.5

V using a switching regulator.

1.2 Output Power Regulators

The available power rails are four fixed supplies at 5 V, 3.3 V, 1.8 V and a negative rail of –5 V. Two

positive adjustable output regulators are also present supplying voltages from 1.4 V to 6.4 V. All output

supplies except for the –5 V output have a rated output current of 1 A. The –5 V output regulator is rated

for 0.36 A.
