TPS54073

At 2.2V - 4.0V, 14A asynchronous buck converters are prohibited during start-up

illustrate

As a member of SWIFT's ™ DC/DC regulator family, the TPS54073 low input voltage high output current synchronous buck PWM converter integrates all the necessary active ingredients. Included in the listed features with substrate is a true, high-performance, voltage-error amplifier capable of selecting output filtered inductor and capacitor components for the highest performance and flexibility; an undervoltage lockout circuit to prevent start-up until the input voltage reaches 35; An internal or externally set slow-start circuit to limit inrush current, as well as a power good output processor/logic reset useful for fault signals and power sequencing.

Based on the reliable precharge output power applied, the current source of the TPS54073 is designed only at startup.
