Tps53353dqpr lson-clip-22 DC-DC power chip
explain
Tps53353 is a d-cap with integrated MOSFET ™ Mode, 20A synchronous buck converter. They are designed for easy-to-use, low number of external components and limited space power systems.
This device features 5.5m Ω / 2.2m Ω integrated MOSFET, * * 1% 0.6V reference and integrated boost switch. Competitive features include: 1.5V to 15V conversion input voltage range, * low number of external components, d-cap for * * * transient response ™ Mode control, automatic skip mode operation, internal soft start control, selectable frequency and no compensation.
The conversion input voltage range is 1.5V to 15V, the power supply voltage range is 4.5V to 25V, and the output voltage range is 0.6V to 5.5V.
The device adopts 5mm × 6mm, 22 pin QFN package with rated operating temperature range of – 40 ° C to 85 ° C.
Tps548b28 is a relatively new 20A device designed for data center applications and has a smaller lead-free package.
