TPS53626数据手册集成电路（IC）的特殊用途稳压器规格书PDF

描述 Description

The TPS53626 device is a driverless, VR13 SVID compliant, synchronous buckcontroller.Advanced control features such as D-CAP+ architecture with overlapping pulse support undershoot reduction (USR) and overshoot reduction(OSR) provide fasttransient response, lowest output capacitance and highefficiency. The device also supportssingle-phase operation in CCM or DCM forlight-load efficiency boost. The device integrates a fullset of VR13 I/Ofeatures including VR_READY (PGOOD), ALERT and VR_HOT.The SVID interface address allows programming from 00h to 07h.Adjustablecontrol of VOUT slew rate can be programmed as high as20mV/uS. Paired with the TI NexFET Power Stage, this totalsolution deliversexceptionally high speed and low switching loss. The TPS53626 also offers four default modes that configure VCCIO and VMCP settings with one single externalresistor to savecomponent count and board space. The TPS53626 device package is a space saving, thermally enhanced 32-pin VQFNpackagethat operates from –40°C to 105°C. For all availablepackages, see the orderable addendum at the end of the document.
