TPS54550PWP

TEXAS INSTRUMENTS  TPS54550PWP.  直流-直流开关降压逐步递减稳压器, 可调, 4.5V-20V输入, 900mV-12V输出, 6A输出, HTSSOP-16

The is a medium output current synchronous buck PWM Converter with integrated high-side MOSFET and a gate driver for low side external MOSFET. Features include a high performance voltage error amplifier that enables maximum performance under transient conditions and flexibility in choosing the output filter inductors and capacitors. The TPS54550 has an under-voltage-lockout circuit to prevent start-up until the input voltage reaches 4.5V, a slow-start circuit to limit in-rush currents and a power good output to indicate valid output conditions. The synchronization feature is configurable as either an input or an output for easy 180° out of phase synchronization. provides evaluation modules and the SWIFT™ designer software tool to aid in quickly achieving high-performance power supply designs to meet aggressive equipment development cycles.
