TPS53513RVER 8A Synchronous Buck Converter 18V 28-VQFN Guide
A technical overview of TPS53513RVER, covering its synchronous buck architecture, electrical specifications, package information, key features, applications, and replacement considerations.
Product Introduction
TPS53513RVER is an 8A synchronous step-down DC/DC buck converter from Texas Instruments. It is designed to efficiently convert a higher DC input voltage into a regulated lower output voltage for digital and power-management systems.
The device supports an input voltage range of 1.5V to 18V and provides an adjustable output voltage from 0.6V to 5.5V. Integrated high-side and low-side MOSFETs help reduce external component count and simplify power-stage design.
TPS53513RVER uses D-CAP3 adaptive on-time control and supports fast load-transient response. The device is particularly suitable for compact point-of-load power supplies where high output current and efficient operation are required.
Key Benefits
8A Continuous Output
The integrated power stage supports up to 8A continuous output current for demanding low-voltage power rails.
Integrated MOSFETs
High-side and low-side MOSFETs are integrated into the device, reducing external power-stage components and PCB area.
Fast Load Response
D-CAP3 control provides fast load-step response without requiring a conventional external compensation network.
Compact Package
The 28-pin VQFN-CLIP package measures approximately 3.5mm × 4.5mm, helping save valuable PCB space.

Package
Package: VQFN-CLIP (RVE)
Pin Count: 28
Package Dimensions: approximately 3.5mm × 4.5mm
Mounting: Surface Mount
Package Type: Exposed-pad VQFN-CLIP
The exposed thermal pad provides an important thermal path and should be connected according to the Texas Instruments PCB layout recommendations.
Pinout
TPS53513RVER uses a 28-pin VQFN-CLIP package with dedicated pins for power input, switching-node connections, feedback, enable, Power Good, mode and frequency configuration, bootstrap, and ground.
Because the TPS53513RVER has multiple power and configuration pins, the exact pin number assignment should be checked against the latest Texas Instruments package drawing before PCB layout.

Equivalent
When selecting a replacement for TPS53513RVER, engineers should compare input-voltage range, output-voltage range, continuous output-current capability, switching frequency, control architecture, integrated MOSFET characteristics, package dimensions, pin assignment, thermal performance, and compensation requirements.
Other 8A synchronous buck converters may provide similar functionality, but a device with the same current rating is not automatically a drop-in replacement. The PCB footprint and pinout should be verified carefully before substitution.
