TPS53515A中文资料1.5-V to 18-V (4.5-V to 25-V bias) Input, 12-A,Single Synchronous Step-Down SWIFT™ Converter数据手册TI规格书

描述 Description

The TPS53515A is a small-sized, synchronous buck converter with an adaptive on-time D-CAP3™ control mode. The device offers ease-of-use and low external-component count for space-conscious power systems.

This device features high-performance integrated MOSFETs, accurate 0.5% 0.6-V reference, and an integrated boost switch. Competitive features include very-low external-component count, fast load transient response, auto-skip mode operation,internal soft-start control, and no requirement for compensation.

A forced continuous conduction mode helps meet tight voltage regulation accuracy requirements for performance DSPs and FPGAs. The TPS53515A is available in a 28-pin QFN package and is specified. from –40°C to +85°C ambient temperature.
