The TMI3388A is a high integrated synchronous step-down converter with up to 8A output current capability and input voltage range from 4.5V to 24V. TMI3388A adopts advance ACOT control architecture, which provides stable operation and has fast transient response performance without complex compensation and low ESR ceramic capacitors. TMI3388A’s output voltage can be adjusted by configuring a divider resistor in the FB pin to meet different output requirements. In addition, TMI3388A integrates very low RDS(ON) MOSFETs and provide excellent efficiency over a range of applications, especially for low output voltages and low duty cycles. TMI3388A also integrates a bypass switch which allows the IC to be powered by external DC source to reduce power consumption. Robust protections are integrated in TMI3388A including cycle-by-cycle current limit, internal soft-start, output OVP and UVP, input UVLO and OTP functions. TMI3388A is available in QFN2.5x2.5-16 package.
