Frequency - Switching: 250kHz ~ 1MHz Operating Temperature: -40°C ~ 85°C (TA)

TPS53353DQPR Integrated Circuit Chip 20A D-CAP™ Mode Synchronous SWIFT™ Buck Converter

TPS53353DQPR Integrated Circuit Chip 20A D-CAP™ Mode Synchronous SWIFT™ Buck Converter

TPS53353DQPR is a D-CAP™ mode, 20-A synchronous switcher with integrated MOSFETs. It is designed for ease of use, low external component count, and space-conscious power systems.

TPS53353DQPR features 5.5-mΩ / 2.2-mΩ integrated MOSFETs, accurate 1%, 0.6-V reference, and integrated boost switch. A sample of competitive features include: a conversion input voltage range from 1.5 V to 15 V, very low external component count, D-CAP™ mode control for super fast transient, auto-skip mode operation, internal soft-start control, selectable frequency, and no need for compensation.
