1 Introduction
The UCC5304EVM-035 device is designed for evaluation of the UCC5304 device, with a 4-A source and
6-A sink peak current for driving Si MOSFETs and GaN FETs. Developed for high voltage applications
where isolation and reliability are required, the UCC5304 device delivers reinforced isolation of 5.7-kVRMS
and a surge immunity tested up to 7.8-kV, with a common mode transient immunity (CMTI) greater than
100 V/ns. The device has an impressive propagation delay of 28 ns and the tightest part-to-part delay
matching in the industry of less than 5 ns, which enables high-switching frequency, greater power density,
and higher efficiency.
The flexible, universal capability of the UCC5304 device, with up to 5.5-V VCCI and 18-V VDD, allows it to
be used as a low-side or high-side driver with independent PWM inputs. With its integrated functions,
advanced protection features (UVLO), and optimized switching performances, the UCC5304 device
enables designers to build smaller, more robust designs for enterprise, telecom, automotive, and industrial
applications, allowing for faster time to market.

2 Description
The UCC5304EVM-035 kit has independent connection points for VCCI and VDD supplies, including
separate ground points. A three-position header with jumpers for the input signal, lets designers easily tie
input high or low. A variety of testing points are provided for easy connection, including some designated
for use with ground springs for shorter measurement loops of key signals. Moreover, the PCB layout is
optimized with minimized loop area in both the gate driver and power supply loops with bypassing
capacitors. For detailed device information, see the UCC5304 4-A/6-A, 5.7-kVRMS Isolated Single-
Channel Reinforced Gate Driver with High Noise Immunity data sheet and Isolated Gate Driver Solutions,
from TI.

4.2.6 Bench Setup Diagram
The current bench setup diagram includes the function generator and oscilloscope connections.
Follow this connection procedure, Figure 2 can be used as a reference.
1. Ensure the output of the function generator and voltage sources are disabled before connection.
2. Connect the function generator channel 1 to TP4 (IN) and TP8 (GND), see Figure 2.
3. Power supply 1: Connect the positive lead to the current meter input of DMM1, and connect the current
meter output of DMM1 to TP12 (VCCI), and negative node applied to TP16 (GND).
4. Power supply 2: Connect the positive lead to the current meter input of DMM2, and connect the current
meter output of DMM2 to TP7 (VDD), and negative node directly to TP15 (VSS).
5. Oscilloscope Ch-1: If a TPP1000 or other ground spring compatible probe is available, attach
oscilloscope channel-1 probe to TP3. Otherwise, connect positive node to TP9 (OUT) and TP13 (VSS).

5 Power Up and Power Down Procedure
5.1 Power Up
1. Before proceeding with the power up test procedure, ensure that the steps in Section 4.2.6 are
complete. Then, Figure 3 can be used as a reference for the expected behavior of the EVM.
2. Enable power supply 1. The quiescent current on DMM1 should be approximately 1mA to 2mA.
3. Enable power supply 2. The quiescent current on DMM2 should be approximately 0.75 mA to 2 mA if
everything is set correctly.
4. Enable the function generator outputs.
5. Verify that the following occurs:
1. Stable pulse output appears on channel 1 in the oscilloscope, see Figure 3.
2. Oscilloscope frequency measurement matches programmed function generator frequency.
3. DMM2 current should read 6.5 ± 0.5 mA with the default 1.8-nF load installed. For more
information about the operating current, see the applications section of the UCC5304 data sheet.
