Texas Instruments Tps61378 Q1 315x180 Ed 042121 Kmr

The TPS61378-Q1 is a fully-integrated synchronous boost converter with load disconnect function integrated. The device is suitable as a post-boost for automotive applications with a programmable current limit up to 4.8-A and maximum 18.5 V output voltage.        

Texas Instruments Lm5156 Q1 315x180 Ed 042121 Kmr

Boost, SEPIC, or flyback? The choice is yours.

The LM5156-Q1 device is a wide input range, non-synchronous boost controller that uses peak current mode control. The device can be used in boost, SEPIC, and flyback topologies and it can help reduce EMI with Dural Random Spread Spectrum technology.
