Abstract
The evaluation board presented in this application note is a 300 W LLC Converter with 400 VDC input and 12 V
output. It is controlled by Infineon’s 2nd generation half-bridge LLC controller ICE2HS01G. The ICE2HS01G is
specially designed for high efficiency applications with synchronous rectification (SR) control on the
secondary side. With new driving techniques, SR can be realized for a half-bridge LLC converter operated
with secondary switching current in both CCM and DCM conditions.
In this application note, the schematic circuit, PCB layout and BOM for the evaluation board are shown,
followed by the performance parameters, such as efficiency and operation waveforms. For the detailed
step-by-step design procedure of this converter, please refer to our design guide [5].

Circuit description
For this evaluation board, only the LLC resonant converter circuit is implemented. Thus, a high voltage DC
voltage should feed directly to the input “+400V” and “PGND” terminals. Additionally, a 15 V DC voltage
needs to be applied to the “PVCC” and “PGNG” terminals to power up the controller ICs.
The input side comprises a NTC, RT100 and a bulk capacitor, C100. The NTC resistor is placed in series with
the input to limit the initial peak inrush current. The bulk capacitor is used to smooth the ripple.
The second stage is a half bridge LLC resonant converter that is operating in zero voltage switching (ZVS)
mode. The controller ICE2HS01G is a 20 pin LLC controller, which incorporates the necessary functions to
drive the half bridge’s high side and low side MOSFETs (Q100 and Q102) by a 50% duty cycle with adjustable
dead time. The switching frequency can be changed by ICE2HS01G to regulate the output voltage against
the load and input voltage variations. During operation, the primary MOSFETs Q100 and Q102
(IPP60R190E6) are turned-on under a ZVS condition and the secondary synchronized MOSFETs Q101 and
Q103 (IPB011N04N) are turned-on and turned-off under a ZCS condition. Hence, very high power conversion
efficiency can be achieved.
The driver circuit is implemented by a 600 V half bridge gate driver IC, IC200 (2EDL05N06PF). As shown in
Figure 4, the IC200 is a 0.5 A 600 V high voltage gate driver IC in an SO-8 package that is used to transmit and
isolate the driver signal to the MOSFETs.
The mains transformer TR100 is used for power pulse transmission whereas a separate resonant choke,
L100 is used for resonant purposes. The transformer configuration for the secondary winding is centertapped and the output synchronized rectifiers MOSFET Q101 and Q103 can reduce the power dissipation
and achieve very high efficiency. The synchronized MOSFETs are controlled by the ICE2HS01G through a
signal pulse transformer TR101 and a dual MOSFET driver IC, IC300.
In the case of a short circuit, the current flowing through the primary winding is detected by the lossless
circuit (C208, C214, D201, D202, R212, and R228) and the resulting signal is fed into the CS Pin of ICE2HS01G.
In the case of an overload, the voltage on the CS pin will exceed an internal 0.8 V threshold that triggers a
protection mode that keeps the current flowing in the circuit at a safe level. In addition, the blanking time
and the restart time can be adjusted by external components.
There are some more control settings in the ICE2HS01G, such as main input under voltage protection, softstart time, frequency setting, dead time setting, synchronized rectifier control, etc. Please refer to the
datasheet and the design guide for details.

Efficiency Measurements
Table 7 shows the output voltage measurements at the nominal input voltage of 400 VDC, with different load
conditions. The input voltage 400 VDC is supplied from a high voltage DC power supply and auxiliary voltage
15 V are applied to the PVCC pin. The RT100 (NTC) is shorted during the test. Before the measurement, 20 ~
30 minutes burn-in are performed.

Soft start at full load and light load
9.1.1
Full load
The output voltage rises to nominal value in around 12 ms and the output overshoot is less than 5%. The
soft start is achieved by decreasing the switching frequency gradually from 280 kHz to 80 kHz until stable
operation is reached.

Burst mode operation at no load
SR soft start at full load
The SR operation is enabled after the output voltage has risen. In ICE2HS01G, SR operation will start with a
small duty cycle, around one-tenth of its normal duty cycle, which will be kept the same for 16 consective
switching cycles. Then, the duty cycle is gradually increased in steps to the full duty cycle. A total of 7 steps
are built in for the soft-start and each step includes 16 switching cycles.

Zero Voltage Switching
With proper design of the LLC converter, ZVS can be realized over the entire load range. In figure 20, Channel 1 shows the
resonant current flowing through the resonant capacitor. Channels 2 and 4 represent the gate-source voltage and drainsource voltage of Q102.
