The QC4.0/4.0+ 18W Mobile Charger enables the design of power supplies featuring low standby power with the output voltage in full regulation, very high-efficiency and high-reliability. The NXP® chipset used is targeting mobile and notebook power supplies with power requirements up to 100W. Supplies can be designed easily and with a minimum number of external components.
The TEA2095 add-on board is designed for incorporation into existing resonant power supplies by replacing the secondary rectifier diodes. The add-on board consists of the TEA2095 Dual SR controller IC and low-ohmic MOSFETs in LFPAK package.
The MAX15038 is a synchronous buck converter which delivers up to 4A load current at output voltages from 0.6V to 90% of VIN. The integrated circuit (IC) supports the input voltage from 2.9V to 5.5V. The total output error is less than ±1% overload, line, and temperature ranges
To meet the increasing demands for isolated Power over Ethernet (PoE) power solutions, Maxim’s power supply experts have developed
Flyback converters are the preferred topology in the SMPS (switched-mode power supply) for medium- and low-power range applications because they are simple and economic. They have less components and are efficient in isolating the output from input. They are used in battery-powered applications, universal AC/DC converters, and industrial and telecommunication equipment. Isolated converters traditionally regulate the output voltage and current by utilizing a secondary side regulation (SSR) composed of an optocoupler and secondary error amplifier.
The MAXREFDES1252 is a No-Opto Flyback converter that delivers up to 1.2A at 14.5V from a 18V to 54V supply voltage. It is designed for industrial equipment that needs isolated voltage from wide input supply voltage.
The MAXREFDES1269 demonstrates how to build a DC-DC buck converter using the MAX20098 step-down controller for 5V DC output applications from a 6V to 36V input. This reference design delivers up to 20A at 5V output. The design uses a six-layer board. Table above shows an overview of the design specification.
The MAXREFDES01261 is a reference design for the asset tracker application based on the Maxim® solution. This reference design is a power management platform for the asset tracker, which includes the MAX32660, MAX77840, MAX77640, and MAX77827. This design demonstrates a small-size, low-power, highly effective, highly accurate, and flexible power management system.
Flyback converters are the preferred topology in isolated converters for medium and low power range applications due to their simplicity and economic considerations. As flyback converters are isolated converters, the output voltage and the current are traditionally regulated by utilizing the secondary side regulation (SSR) composed of an optocoupler and a secondary-error amplifier.
The MAXREFDES9000 is a reference design showcasing the DS28E18 that demonstrates how to both operate and power remote I2C and serial peripheral interface (SPI) sensors using only two wires
The MAXREFDES1084 is a miniature, 24V output, isolated power supply that can deliver up to 0.5A of load current. The design uses the MAX17596 peak-currentmode controller in discontinuous-conduction mode (DCM) flyback topology running at 125kHz. The input voltage range of the MAX17596 is 4.5V to 36V. However, an extra bias winding from the transformer is used to power the controller. This allows the input operating voltage to go up to 60V for this design.
The MAXREFDES1202 is a dual-phase, buck converter reference design developed using the MAX17558, MAX15019A, and MAX17552. This reference design is rated to operate over a wide input voltage range from 15V to 55V. The design can deliver an output power of 360W at 12V.
The MAXREFDES1244 is a No-Opto Flyback converter that delivers up to 1.2A at 5V from a 18V to 54V supply voltage. It is designed for industrial equipment that needs isolated voltage from wide input supply voltage.
