TDA21535
Description
- High frequency, low profile DC-DC converters;
- Voltage Regulators for DDR memory arrays, and low current voltage rails;
The TDA21535 integrated power-stage contains a low quiescent current synchronous buck gate-driver IC which is co-packed with control and synchronous MOSFETs along with an active diode structure that achieves low Vsd similar to a schottky with very little reverse recovery charge. The package is optimized for PCB layout, heat transfer, driver/MOSFET control timing, and minimal switch node ringing when layout guidelines are followed. The paired gate driver and MOSFET bination enables higher efficiency at lower output voltages.
The internal MOSFET sensing achieves superior current sense accuracy vs. best-in-class controller-based Inductor DCR sense methods.
Protection includes IC temperature reporting and over temperature protection feature
(OTP with thermal shutdown), cycle-by-cycle over current protection (OCP), control MOSFET short detection (HSS
