TDA21535 - low profile DC-DC converters

General 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 al

Key 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, high-side MOSFET and low-side MOSFET.
  • Input voltage range of 4.25 V to 16 V.
  • VCC supply of 4.25 V to 5.5 V.

TDA21535 1 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 combination enables higher efficiency at lower output voltages. The internal MOSFET sensing achieves superior current sense accuracy vs.
