DC/DC控制器, 同步降压, 降压, 4.5 V至28 V电源, 1 MHz, VQFN-32
The TPS53627 device is a driverless, VR13 SVID compliant, synchronous buck controller. Advanced control features such as D-CAP+ ™architecture with overlapping pulse support undershoot reduction USR and overshoot reduction OSR to provide fast transient response, lowest output capacitance and high efficiency. The device also supports single-phase operation in CCM and DCM operation for light-load efficiency boost. The device integrates a full set of VR13 I/O features including VR_READY PGOOD, ALERT and VR_HOT. The SVID interface address allows programming from 00h to 07h. Adjustable control of VOUT slew rate can be programmed as high as 20mV/uS.
Paired with the NexFET™ Power Stage, this total solution delivers exceptionally high speed and low switching loss.
The TPS53627 device package is a space saving, thermally enhanced 32-pin VQFN package that operates from –40°C to +105°C.
