  • PMP7769 700V-860V input to 16.5V@0.5A output | TI.com
    PMP7769: Circuit is a non isolated flyback converter. Vin is 700V to 800V max, converting to 16.5V out at a maximum current of 500mA. The design utilizes an external Error amplifier using an LMC7101 for feedback control. The circuit also uses U102 and Q101(and resistors etc etc…) as an external UVLO circuit. LM5021 features include an ultra-low (25 µA) start-up current, which minimizes power losses in the high voltage start-up network. A skip cycle mode reduces power consumption with light loads for energy conserving applications.

  • LOADDETECTPWRSUPPLY-REF Load Detecting Power Supply | TI.com
    LOADDETECTPWRSUPPLY-REF: Every year, millions of Watts are lost in heat from inefficient linear AC/DC wall adapters. This loss is incurred even when there is no load applied. The cause of this inefficiency is that energy is being lost from leakage elements found in the transformer and electrolytic capacitors. This reference design shows that by using a SMPS instead of a linear supply, you can drastically reduce the amount of wasted energy and by adding some additional circuitry that “wakes” up the supply when a load is applied, losses drop to a few milliwatts. The wake on load AC/DC power adapter is a wall mount power supply which converts 100-240Vac to 5Vdc at 500mA to a USB port. The typical application for this type of AC/DC adapter is a cell phone charger. The unique feature of this power adapter is extremely low power consumption when the output is not loaded. This power adapter uses Texas Instruments' LM5021 PWM controller and has a load detection and shutdown circuit which turns off the PWM IC at no load. It won’t restart until the output is loaded ( wake on load ) or the output capacitor is discharged to a certain level. The start up circuit is designed to consume less than 40uA current at high line input during shutdown period. By doing so, the no load power consumption of this adapter can be greatly reduced.

  • PMP10215 Universal Input to 3.3V, 12V, 36V, 200W Continuous PSU for Class-D Amplifier Reference Design | TI.com
    PMP10215: This power module generates all voltages to supply a class-D audio amplifier. The main output voltage is 36V and delivers 200W continuously and 840W peak. The first stage is a power-factor corrected Boost. A Flyback converter supplies 12V on primary side as well as 12V@300mA and 3.3V@200mA on secondary side. A hardware switch + remote input let the converter enter in stand-by mode: in this status the 36V output is disabled and 12V, 3.3V are "always on". This way the stand-by power is reduced down to 150mW @ 115Vac and 270mW @ 230Vac. A second digital input switches the main output voltage from 36V to 18V, allowing low current consumption mode in case of the audio amplifier needs less power.
