TDA21590 Product details

Description

High frequency, low profile DC-DC converters; Voltage Regulators for CPUs, GPUs and DDR memory arrays; Telecom controlled and uncontrolled The TDA21590 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 tra

Features

"refreshing" of bootstrap capacitor to prevent the bootstrap capacitor from over-discharging. Operation of up to 1.5 MHz switching frequency enables high performance transient response, allowing miniaturization of output inductors, as well as input and output capacitors while maintaining industry leading efficiency. Features.
Integrated driver, active diode, control MOSFET Q1 and synchronous MOSFET Q2.
On-chip MOSFET Current sensing and reporting at 5 µA/A.
Input vol.
