TPS7H4003EVM Overview
1 TPS7H4003EVM Overview
The TPS7H4003-SEP is a radiation hardened, 7-V, 18-A synchronous step-down converter with integrated highside and low-side MOSFETs. High efficiency and efficient usage of space are achieved through low resistance
MOSFETs and a current mode control implementation.
The EVM is configured in a default state to accept a 5-V input but can be modified to disable or change the
under voltage lock out (UVLO) protection, allowing for any input voltage from 3 V to 7 V. The EVM is also
configured for a 1-V output at a maximum peak output current of 18 A. Again, the regulated output voltage can
be modified by changing one resistor on the board. The TSP7H4003-SEP has a dedicated soft start, enable, and
adjustable slope compensation pins providing design flexibility to meet specific application requirements.
Finally, as shown in Figure 1-1, this EVM supports a single POL channel. However, the device does support
parallel operation. With four POLs operating in quadrature phases, a 72-A load current can theoretically be
provided.

TPS7H4003EVM Initial Setup
3 TPS7H4003EVM Initial Setup
This section provides the test instruments required and the connections to the EVM.
1. Input DC power supply
a. Set for 5-V DC, 8-A current limit.
b. Connect positive output of DC supply to pin 1 of connector J1 (PVIN) and negative terminal of supply to
pin 2 of connector J1 for ground using 16 AWG wire or larger.
• NOTE: For more precise measurements, eliminating the IR voltage drop in the input cables is
achieved by using a power supply source with sensing ports and connecting between TP2 to PVIN
and TP1 to GND.
2. DC electronic load
a. Connect positive DC input of e-load to pin 1, VOUT, of connector J7 (VOUT) using 16 AWG wire.
• NOTE: Wire from pin 1, positive terminal of connector, to the e-load should include at least some part
in which the wire gauge can be strapped by the oscilloscope current probe. This will eliminate the
need for a setup change to cover all tests.
b. Connect negative DC input of e-load to pin 2, PGND, of connector J7 (VOUT) using 16 AWG wire.
c. Connect voltage monitoring sensing ports of e-load across test points TP12 (VOUT1) and TP13 (PGND).
A voltage meter can be used to monitor this voltage also.
3. Oscilloscope
a. CH1 - Connect voltage scope probe to scope probe test point J5 (PH) to monitor the phase node. DC
coupled, Full BW, 2 V/div, Rising Edge Trigger at 0.5 V.
b. CH2 - Connect voltage scope probe to scope probe test point J6 (VOUT) to monitor the output voltage.
AC coupled, BW = 20 MHz, 10 mV/div.
c. CH4 - Connect current scope probe to monitor current through wire connecting J7 (VOUT) and e-load. 5
A/div.
• NOTE: Only required for transient load testing.

4.5 Loop Frequency Response
Measuring the frequency response of the feedback loop requires a unique test setup as well as physical
changes to the EVM. 0-Ω resistor jumper R8, below TP9 (BODE) test point and circled in yellow in the graphic
below, must be lifted in order to break the loop. Both test points TP9 (BODE) and TP10 (VOUT) will be used for
connections to the Bode100 instruments.

4.6 Setup
The test setup, which includes several connections to Picotest Bode100 test instruments, is shown in Figure 4-7
with measurement results shown in Figure 4-8. The CHF, high frequency pole, component of the compensation
circuit is optional. Omitting it will result in slightly increased phase margin. However, the benefit of including it is
that the gain curve is set in a downward trajectory as frequency increases, making a monotonic gain curve more
likely to be achieved.
