Texas Instruments' TPS53626 device is a driverless, synchronous VR13 SVID buck controller. Advanced control functions, such as D-CAP + architecture with overlapping pulse support, support for undershoot reduction (USR) and overshoot reduction (OSR), provide fast transient response, lowest output capacitance and high efficiency. The device also supports single-phase operation in CCM or DCM to improve light-load efficiency. The device integrates full VR13 I / O functions including VR_READY (PGOOD), ALERT and VR_HOT. The SVID interface address allows programming from 00h to 07h. The adjustable control of VOUT slew rate can be set up to 20mV / uS.
Used in conjunction with TI NexFET power stages, this total solution provides extremely high speeds and low switching losses. It also provides four default modes that configure VCCIO and VMCP settings with an external resistor to save component count and board space.
The device package is a space-saving, thermally enhanced 32-pin VQFN package that operates from –40C to 105C.
