L5953 - Multiple switching voltage regulator

Description

The L5953 is the integration of one switching regulator, two linear voltage regulators, two low voltage warnings and two high side drivers.

It has a stand-by operation mode (low current consumption) where only the stand-by voltage regulator plus the low voltage warnings are active.

Features

  • PWM: adjustable 2.5/10V - 1A switching voltage regulator External POWER MOS ability for output current enhancement Synchronization function REG1- Linear low drop 3.3/5V - 250mA STBY voltage regulator (low current consumption) with RESET REG2- Linear voltage regulator 1.5V to 3.3V externally adjustable - 300mA maximum current HSD1 : 500mA High side driver HSD2 : 200mA High side driver SPI Interface SPI Diagnostics HSD1, HSD2 Double switching frequency SPI selectable Doubl.
