12-V / 100-A negative-to-positive synchronous buck-boost reference design for power amplifiers
This reference design is a negative-to-positive synchronous buck-boost converter for power amplifier applications. The circuit is powered from the nominal -48-V system source to provide an output voltage of +12 V at 100 A. The design uses two dual synchronous boost controllers for 4-phase operation at a switching frequency of 100 kHz. Output voltage adjustment to +14.5 V is jumper selectable. 1- through 4-phase operation is also jumper selectable.

2460-W bidirectional boost converter reference design for automotive applications
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.

1000-W: Bidirectional: 12-V to 12-V Converter Reference Design
This reference design is a dual-channel: bidirectional converter suitable for 12-V to 12-V: dual-battery system: automotive applications. This reference design has a wide input range (3 V to 40 V) and could give full load (1kW) in the input voltage from 9V to 18V by using two LM5170-Q1 controllers. The efficiency is up to 98% at Vin = 18V: Vout = 12V: Iout = 40A.
