Part Details for LM5001 by Texas Instruments

This reference design is a 2460-W bidirectional boost converter for automotive applications. The circuit is powered from the nominal 12-V battery to provide an output voltage of 48 V at 51.25 A. The design uses two dual-phase synchronous bidirectional controllers operating at a switching frequency of 200 kHz per phase. The 48-V output is designed to drive a motor. When the load current reverses and the output voltage reaches 54 V: hysteretic direction control allows the load current to be returned to the 12-V battery. Normal boost operation resumes when the output voltage returns to 48 V. Mounting holes are provided for a bottom-side heat sink underneath the MOSFETs.

This reference design provides a tiny auxiliary +12-V supply for general purpose. In this case: SEPIC topology supports wide input range from 6 V to 60 V. Even at inputs as low as 3.5 V: this reference design is able to provide half of the output power. Another benefit of SEPIC is low reflected ripple: resulting in less conducted emissions. The small magnetizing inductance sets right half plane zero fairly high: so loop bandwidth can be increased and allows a small output capacitance by keeping good transient response.

This reference design provides accurate measurements of AC voltage and current inputs using a precision 16-bit SAR ADC over a wide input range: covering protection and measurement range (including sampling requirements of IEC 61850-9-2): simplifying system design and improving trip time performance and reliability. The analog input module (AIM) is isolated from the host processor using a digital isolator with an integrated power. For a limited function and cost optimized  design approach: An AC AIM can be designed using only three TI products: reducing system cost and board size. The alarm feature identifies the AC analog input faults on a sample basis for faster fault detection. The ADC has an additional auxiliary channel to diagnose the supply output of the digital isolator. A 12-bit ADS8668 ADC with a gain amplifier can increase the dynamic range by using programmable internal ranges: further optimizing the system cost.

A very low noise differential power supply for split rail systems requiring low noise +5V and -5V (higher or lower voltage is possible). This design is fully isolated and capable of floating to over 500V differential from Vin to Vout (higher is possible). The LM5001 IC is a fully integrated flyback regulator which performs all of the current mode control for tight regulation and transient response. The design is small and uses only one side of a double sided FR4 PCB for components. Smaller IC packages are available so the layout can be further optimized.This design provides very low noise bias rails for ground referenced analog circuitry (under 20 mV p-p total noise up to 1GHz). The design utilizes a very small size PCB footprint. This approach is ideal for many applications including low noise cable drivers: medical electronics: high fidelity low power audio: and other sensitive circuitry that can benefit from very low noise split rail biasing. Input to output isolation is employed for those applications where the input and output voltages might be at different potentials or when the input voltage travels across cabling which might pickup noise. The floating outputs avoid unwanted ground currents and the potential for additional noise pickup. For those that do not require isolation they can remove the feedback isolation section of the design and use a simple resistor divider for setting the feedback voltage.

In some cases a scope or spectrum analyzer does not have the range required to measure very small noise levels.  This noise measurement post-amp boosts the output noise of the device under test (DUT) to allow for measurement with standard test equipment. The key requirements of this circuit

TIDA-00500 is a reference design to provide power to load for short duration of time after a power interrupt has occurred. Traditionally Programmable Logic Controllers (PLCs) are equipped with a recharge battery source for alternative power. This battery source often suffers from drawbacks like complex charging topologies: charging time: periodic maintenance: and eco-hazards. In scenarios where PLCs need to be functional for a short duration of time after power interrupt: a capacitor based backup is a much simpler and more effective approach because of the higher power density in comparison to a standard battery-based solution.
