The TMI3388C is a high integrated synchronous  step-down converter with up to 8A output current  capability and input voltage range from 5.5V to 24V.  It integrates very low RDS(ON) MOSFETs to  minimize the conduction loss.TMI3388C adopts  advance ACOT control architecture, which provides  stable operation and has fast transient response  performance without complex compensation and  low ESR ceramic capacitors. At light loads, The  TMI3388C can be operated in two modes, the USM  mode can provide lower noise and the PFM mode  can provide higher efficiency. In addition, TMI3388C  Integrated two divider feedback resistance and  offers 5.1V Fixed Output Voltage. The TMI3388C  also provide a fixed 5V LDO with 100mA current  capability, which can be used to power the external  peripheries. Besides, the 5V LDO can switch over to  Buck regulator output to save power loss. It has two  EN pins control LDO and Buck regulators  respectively. Robust protections are integrated in  TMI3388C including cycle-by-cycle current limit,  internal soft-start, output OVP and UVP, input UVLO  and OTP functions. TMI3388C is available in QFN2.5x2.5-16 package.
