10A boost converter for high-power portable and industrial rails
It accepts an input voltage from 2.7V up to 20V and delivers an adjustable output up to 20V, making it suitable for applications ranging from single-cell Li-ion boost to multi-cell battery backup and USB-C power delivery.
Switching frequency and synchronous rectification trade-offs
Synchronous rectification is built in, which improves efficiency at higher output currents by replacing the freewheeling diode with a low-Rds(on) FET. The single-output, positive-configuration regulator uses an adjustable feedback loop; the minimum fixed output voltage is 4.5V, so the part can bootstrap from a 5V rail or generate a 5V output from a lower input.
Package and thermal considerations for the 13-VQFN-HR
Given the 10A switch current, the PCB layout should use short, wide traces for the power path and place the input and output capacitors close to the IC to minimise parasitic inductance.
For dual-sourcing or second-source evaluation, the base product number TPS61178 covers a family of pin-compatible variants with different current ratings and feature sets; confirm the specific output current and switching frequency range against the BOM requirement.
