Introduction
The LM381-Flyback Evaluation Module helps designers evaluate the operation and performance of the
LM3481 boost controller in an isolated flyback design with a wide input voltage. The design accepts an
input voltage range of 5 V to 32 V and provides an isolated output of 12 Vout capable of supplying 2 A of
current to the load. The switching frequency is externally set at a nominal 130 kHz.
Figure 1. LM3481-Flyback Evaluation Board – Top View
The LM3481 device is a versatile low-side N-FET high-performance controller for switching regulators.
The device is designed for use in Boost, SEPIC, and Flyback converters and topologies requiring a lowside FET as the primary switch. The switching frequency of the LM3481 device can be adjusted to any
value between 100 kHz and 1 MHz by using a single external resistor or by synchronizing it to an external
clock. Current mode control provides superior bandwidth and transient response in addition to cycle-bycycle current limiting. Current limit can be programmed with a single external resistor. The LM3481 data
sheet (SNVS346) gives a complete description of the part, operation, and application information.

Test Bench Setup
Figure 2. Test Bench Setup
Figure 2 shows a typical test bench setup for the LM3481-FlybackEVM. The power supply and the load
should be capable of handling the input and output voltage and current rating of the board. Follow these
steps to properly set up the LM3481-FlybackEVM.
1. Connect the power and ground connectors VIN (J1) and GND (J2) to the power supply.
2. Connect an ammeter in series with the input if needed.
3. Connect a voltmeter across the input terminals (Vin, TP_GND).
4. Connect a resistive load or an electronic load across terminals VOUT (J3) and ISO GND (J4).
5. An ammeter can be inserted in series with the load to observe the load current.
6. Connect a voltmeter across the output sense terminals (Vout, ISOGND) to observe the output voltage.
7. With the load initially set to no load, set the power supply between 5 V and 32 V and turn on the power
supply. Check for 12 V at the output.
8. Once the output is at the expected target (12 V), increase the load gradually within the operating range
(0–2 A).

Figure 5 shows the LM3481-FlybackEVM response to load transients. The current step is from 50% to
100% of maximum rated load at VIN = 12 V. The current step slew rate is 70 mA/µs. Total peak-to-peak
voltage variations is as shown, including ripple and noise on the output. Figure 6 shows the LM3481FlybackEVM loop-response characteristics. Gain and phase plots are shown for VIN voltage of 12 V with
load current of 2 A. The loop-response measurement is taken by replacing R8 with a 49.9-Ω resistor. The
signal is then injected across R8 with test points Loop_1 and Loop_2.
