TPS53315

illustrate

TPS53315 is a D-D ™ mode with 12 synchronous switches with integrated MOSFETs. It is designed for ease of use, a small number of external components, and a small package powertrain.

The device features single-rail input support, a 19mΩ and a 7mΩ integrated MOSFET, accurate 1%, 0.6-V reference, and an integrated boost switch. A competitive sample of features includes: >96%, maximum efficiency, wide input voltage range from 3 V to 15 V, very low number of external components, ultra-fast transient mode control, optional ™ auto-skip and PWM operation, internal soft-start control, adjustable frequency, and no need for compensation.

The conversion input voltage range is from 3 V to 15 V, and the supply voltage range is from 4 points.
