This reference design is a power supply solution for reverse powered telecom applications. Up to 8 isolated inputs provide a universal output; the load is shared equally among all active converters.
The PMP10110 is designed to convert universal input AC voltage to an isolated 17V...30V@6A, suitable for charging lead-acid and lithium-ion batteries. The converter is a constant voltage and constant current generator, the set points for output voltage (charge level) and current can be set via two PWM signals. The first stage is the PFC boost stage, while isolation and current stabilization are performed by the DC-DC half-bridge stage. The isolated quasi-resonant flyback converter provides all internal voltages and some additional current to the external load (fan or analog section), specifically 12V@400mA and 5V@300mA.
The PMP10116 reference design utilizes the UCC28063A conversion mode PFC controller to drive LEDs up to 700mA from the AC input. This flyback PFC topology provides isolation and uses quasi-resonant mode control. It supports analog dimming at the output. See UCC28060 Interleaved AC-DC Single-Stage Flyback-Based LED Driver for design guidelines
This power module generates all the voltages required to power the Class D audio amplifier. The main output voltage is 36V, which provides 200W of continuous power and 540W of peak power. The first stage is a power factor correction boost. The flyback converter provides 12V on the primary side and 12V (300mA) and 3.3V (200mA) on the secondary side. Using a hardware switch and remote input, the converter can enter standby mode: in this state, the 36V output is disabled and 12V, 3.3V are "always on". In this way, the standby power can be reduced to 150mW (115Vac) and 270mW (230Vac). A second digital input switches the main input voltage from 36V to 18V, allowing it to enter a low-current consumption mode when the audio amplifier requires less power.
This efficient, high-power reference design uses the LM5119 dual-phase synchronous buck controller to regulate 14.4V at 60A. This design can be used to feed a single vehicle battery source from a dual-battery system commonly found in trucks. Features include input EMI filtering, output hot-swap protection, input/output current monitoring, and temperature monitoring.

The PMP10733 uses the LM5160 in a Fly-Buck-Boost topology with the primary side set to a negative voltage. Setting the primary side to a negative voltage reduces the turns ratio of the transformer and therefore allows for better line and load regulation. The primary and secondary voltages are set to negative 15V and positive 15V respectively. The maximum operating current on the primary and secondary voltage rails is set to 150mA. The switching frequency is set to 200kHz.
The PMP10748 is a complete automotive front-end protection TIDesign featuring TI's Zero IQ smart diode controller and high-side protection controller. This design utilizes two LM74610-Q1 ICs to drive 40V MOSFETs in an OR-ing configuration to provide reverse polarity protection. The LM74610-Q1 is a high-efficiency, zero-IQ alternative to lossy diode and inefficient PFET solutions, providing reverse polarity protection. The design also provides programmable OVP, UVLO and OCP through the LM5060-Q1 high-side protection controller. With the LM5060-Q1, this design not only has controllable rise time for safe connections, but also has programmable fault detection delay time.
