TDA21490 - low profile dc-dc converters

General Description

High frequency, low profile dc-dc converters

The TDA21490 power stage contains a low quiescent-current synchronous buck gate-driver IC co-packaged with high-side and low-side MOSFETs.

Key Features

  • auto-replenishment of the bootstrap capacitor to prevent over-discharging. The TDA21490 features a deep-sleep power saving mode, which greatly reduces the power consumption when the multiphase system enters PS3/PS4 mode. Operation at switching frequency as high as 1.5 MHz enables high performance transient response, allowing reduction of output inductance and output capacitance values while maintaining industry leading efficiency. The TDA21490 is optimized for CPU core power delivery in server a.

TDA21490 OptiMOSTM Power Stage TDA21490 1 Description  High frequency, low profile dc-dc converters  Voltage Regulators for CPUs, GPUs, and high current rails The TDA21490 power stage contains a low quiescent-current synchronous buck gate-driver IC co-packaged with high-side and low-side MOSFETs. The package is optimized for PCB layout, heat transfer, driver/MOSFET control timing, and minimal switch node ringing when layout guidelines are followed. The gate driver and MOSFET combination enables higher efficiency at the lower output voltages required by cutting edge CPU, GPU and DDR memory designs.
