2 DESCRIPTION
As a member of the SWIFTв„ў family of dc/dc
regulators, the TPS5430 is a high-output-current
pulse-width modulation (PWM) converter that
integrates a low-resistance high-side N-channel
MOSFET. Included on the substrate with the listed
features are a high-performance voltage error
amplifier that provides tight voltage regulation …
