This is a reference design for a 65W USB-PD type C charger with a small form factor. Reference designs are designed to demonstrate performance by meeting various industry specifications and allowing for small form factor design requirements. Using Infineon digital flyback controller XDPS21081, 600V CoolMOS™ C7 superjunction MOSFET (IPL60R185C7), OptiMOS™ PD synchronous rectification MOSFET (BSC0802LS), 30V OptiMOS™ MOSFET (BSZ0905PNS) as a safety switch, small signal MOSFET (BSL606SN) and the EZ-PD™ CCG3PA USB Type-C controller.
This reference design is a power stage for brushless motors in battery-powered garden tools and power tools rated up to 1 kW, powered by a 10-cell lithium-ion battery with a voltage range of 36 to 42 V. This design uses 60V N-channel NexFET(TM) with ultra-low drain-to-source resistance (RDS_ON) of 1.8 mΩ in a SON5x6 SMD package, resulting in a small 57 × 59 mm PCB footprint. This design uses a three-phase gate driver to drive the three-phase MOSFET bridge, which can operate from 6V to 60V and supports programmable gate current with a maximum setting of 2.3A sink/1.7A source. The C2000™ Piccolo™ LaunchPad™ LAUNCHXL-F28027 is used with this power stage and implements 120-degree trapezoidal control of BLDC motors via Hall sensors in software. The gate driver's cycle-by-cycle current limiting feature limits the maximum current allowed in this power stage to a safe level, thereby protecting the board from overcurrent issues caused during motor shutdown.
Maxim's MAXREFDES36# reference design is an IO-Link, low-power, 16-channel digital input hub compliant with IEC 61131-9. It contains two octal digital input serializers, an IO-Link transceiver and efficient step-down converter. The entire design fits in a standard DIN rail printed circuit board (PCB) holder.
This reference design is a high efficiency, high power density and light weight resonant converter reference design. It converts a 390V input to a 48V/1kW output. The PMP20637 power stage has over 140W/in^3 power density. The whole board weight is less than 210g. With fixed 950kHz switching frequency in steady state, 97.6% peak efficiency is achieved.
This evaluation kit supports the fully integrated MC34717EP Dual Switch-Mode Power Supply—a dual-synchronous, buck-switching regulator.
This reference design delivers an accurate output current limit solution for the TPS61088 boost converter. This feature is realized by an output current sense resistor and a low cost operational amplifier. When the output current is higher than the current limit point, the output of the operational amplifier will be higher than the TPS61088’s 1.204V reference voltage. So the output voltage drops. If the output current continuously increases, the output voltage will be further decreased. Thus the maximum output power will always be limited below a certain level.
The USB Type-C™ and Power Delivery (PD) MicroDock Evaluation Module (EVM) provides a complete USB Type-C dock reference solution including audio, USB data, power delivery and video. The EVM has a small 2-inch × 4-inch form factor and supports both sourcing and sinking power capabilities through the USB Type-C PD host port. Video output capabilities include DisplayPort and HDMI.
The PMP15007 uses the LM5161-Q1 in Fly-Buck topology with both primary and secondary output voltages set to 5V nominal. This circuit can accommodate a voltage input range of 36V to 72V, making it ideal for a 48V nominal input voltage rail. The primary side is set to 5.32V nominal and the secondary isolation side is 5V with feedback resistors and is based on Coilcraft LPD8035V series coupled inductors set to a 1:1 turns ratio. The maximum operating current is set to 225mA on both the primary and secondary voltage rails. The switching frequency is set to 315kHz nominal.
3W 5V Flyback 180 to 265VAC Reference Design An offline isolated 3W 5V power supply based on the CoolSET™ ICE3RBR4765JG current mode controller.
This TI Precision Verified Design provides the principles, component selection, simulation, PCB design and measurement details for a single-ended input of a specific differential output circuit that converts a single-ended input from +0.1V to +2.4V ±2.3V differential output on a single +2.7V supply. The output range is specifically limited to maximize its linearity. This circuit consists of 2 amplifiers. An amplifier acts as a buffer, creating the voltage Vout+. The second amplifier inverts the input and increases the reference voltage to produce Vout-. Both Vout+ and Vout- range from 0.1V to 2.4V. The voltage difference Vdiff is the difference between Vout+ and Vout-. This will give a differential output voltage range of +2.3V.

This verification design utilizes a triangle wave generator and comparator to generate a pulse-width modulated (PWM) waveform with a duty cycle that is inversely proportional to the input voltage. The op amp and comparator generate a triangular waveform, which is then passed to one input of the comparator. By passing the input voltage to the other comparator inputs, a PWM waveform is generated. Negative feedback from the PWM waveform to the error amplifier is used to ensure high accuracy and linearity of the output. This design was constructed using the OPA2365 op amp, TLV3502 comparator, and REF3325 reference. Learn more about TI's high-precision designs
