The TMI3🎃388C is a high ꦜintegrated synchronous step-down converter with uꦏp to 8A output current capability and input voltage range from 5.5V 🐼to 24V. It integrates very low RDS(ON) MOSFETs to minimize the cond🌠uction losওs.TMI3388C adopts advance ACOT control architecture, 👍which prov🍨ides stable o♉peration and has fast transient res༺ponse performancওe without complex compensation and low ESR ceramic capacitors. At light loads﷽, The TMI3388C can be operated in two modes, the USM &nbsꦐp;mode can provide lower noise and the♏ PFM modꦚe can provide higher efficien෴cy. In addition, TMI3388C Integrated two divider feedback resistance and &nbsꦛp;offers 5.1V Fixed Output Voltage. Th✅e TMI3388C also ꦍprovide a fixed🍷 5V LDO with 100mA current capability, which can be useღd to power the external peripheries. 💛Besides, the 5V LDO can switch oveꦗr to Buck🎶 regulator output to save power loss. It ha🌊s two EN pins control LDO and Buck regulators respectiveꦑly. 𓆉Robust protections are integrated in TMI3388C including cycle-by-cycle cur🗹rent limit, internal sꦓoft-start, output OVP and UVP, input UVLO and OTP functions. TMI3388C is available in QFN2.5x2.5-16 package.
