The TDA21535 from Infineon Technologies is a high-frequency, low-profile DC-DC converter designed for voltage regulation in DDR memory arrays and low current voltage rails. This integrated power stage features a synchronous buck gate-driver IC co-packed with control and synchronous MOSFETs, along with an active diode structure.
Key electrical specifications include an input voltage range of 4.25 V to 16 V and a VCC supply range of 4.25 V to 5.5 V. The output voltage can be adjusted from 0.225 V up to 5.5 V, with a significant output current capability of 35 A. The device supports operation up to 1.5 MHz switching frequency, enabling high performance transient response and allowing for miniaturization of external components.
Protection features include cycle-by-cycle over current protection (OCP), IC temperature reporting, over temperature protection (OTP) with thermal shutdown, control MOSFET short detection (HSS), and VDRV and bootstrap under-voltage protection. The TDA21535 also includes auto-replenishment for the bootstrap capacitor.
The component is housed in a compact 4 mm x 5 mm x 0.9 mm PQFN package, optimized for PCB layout and heat transfer. It is lead-free and RoHS compliant.
