The device includes an oscillator that drives two internal FETs via an internal gate drive circuit. The gate drive circuitry provides two complimentary output signals that turn the output transistors on and off. The oscillator’s output frequency is set by RSET, and then internally divided by two to drive the transistors with a 50/50 duty cycle. Operation of a Push-Pull Converter N EW Push-pull converters use center tapped transformers to transfer power from the primary to the secondary. The PE22100 contains two FETs to ground, represented by SW1 and SW2, which operate in two phases as shown in Figure 16. D1 1 4 V+ 2 3 FO R 3 D2 SW2 1 SW1 EN SW1 2 D ED V+ D1 D2 SW2 Phase 2 Figure 16. PE 22100 Operating Modes(*) M M Phase 1 4 EC O Note (*): The numbers and colors in the figure correspond to the scope plot in Figure 17. In Phase 1, the primary is energized ( 1 ) via SW2 being switched "ON" to ground. Then, during Phase 2, when SW2 is switched "OFF", the stored energy transfers ( 2 ) to the output capacitor via D2. R In Phase 2, the primary is energized ( 3 ) via SW1 being switched "ON" to ground. Then, during Phase 1, when SW1 is switched "OFF", the stored energy transfers ( 4 ) to the output capacitor via D1. N O T Cycling between Phases 1 and 2 continuously ensures that current is supplied to the output capacitor. http://www.murata.com/products/power Copyright ©2020 pSemi Corporation, a Murata company.

Compatible Transformers Current Limit and Over-Temperature Detection FO R The PE22100 contains a built-in current limit feature. If the current in either OUTA or OUTB to GND exceeds 600 mA, both outputs will enter over-current mode. In over-current mode, the outputs continue to switch on and off in antiphase, but at a reduced over-current mode of 320 mA. Both outputs maintain this current limit for 4096 clock cycles, as set by CSET, or until the over-temperature detection threshold is crossed, whichever occurs first. D ED After 4096 clock cycles, the current limit is checked again. • If the current limit is below the threshold, the PE22100 exits current limit mode. • If the current limit is above the current limit threshold, the PE22100 enters current limit mode for another 4096 clock cycles. N O T R EC O M M EN If the die temperature exceeds +140°C, the internal FETs switch off, forming an open circuit at OUTA and OUTB. The temperature detector has an approximate hysteresis of +3.4°C. As the temperature falls below the threshold, OUTA and OUTB resume normal operation. http://www.murata.com/products/power Copyright ©2020 pSemi Corporation, a Murata company. All rights reserved.

The charge and discharge current are set by the RSET value (see Figure 18). This forms an oscillator that charges and discharges capacitor CSET between 1.0V and 1.5V. + – DIVIDE BY 2 CLOCK 1.0V + – + – 1.5V D ED 37.5 µA FO R CSET N EW 37.5 µA EN Figure 18. Internal Oscillator Structure Frequency = 37.5 µA M CSET M To calculate the oscillator frequency at CSET: EC O For example, the oscillator frequency at CSET for an external capacitor of 100 pF will be: Frequency = 37.5 µA = CSET 37.5 x 10-6 100 x 10 = 375 kHz -12 R Internally, the PE22100 divides this value by a factor of 2, for an internal oscillator frequency of 375/2 = 187.5 kHz. This is the frequency that drives the output transistors. N O T The PE22100 can be driven up to rates of 2 MHz at CSET. As CSET is decreased, be sure external PCB stray capacitances do not introduce errors into the oscillator frequency. http://www.murata.com/products/power Copyright ©2020 pSemi Corporation, a Murata company.

In this application, the output is further regulated by a linear regulator to provide an isolated regulated supply for the transceivers. The efficiency loss due to the linear regulator should be taken into account for the system efficiency calculation. At low load currents, switching transitions from the primary side can be capacitively coupled to the secondary side. Adding a Zener diode across the output voltage will clamp this voltage. 5V N EW 100 nF OUTPUT VOLTAGE VDO OUTA VREG MBR0520 LDO LDO 5V 470 nF 10 µF 0.1 µF R 10 µF PE22100 100 pF 82 kΩ OSCILLATOR OUTB EN GND GND M EN D ED SGND ISOLATION BARRIER RSET FO MBR0520 CSET DATA OPTO COUPLERS DATA TRANSCEIVER RS485 CAN RS232 Figure 19.
