Description
STw4510 is a 7-channel integrated power management device for application powered by one Li-Ion or Li-Polymer cell. STw4510 embeds 2 highly efficient step-down DC/DC converters and 5 LDO regulators.
It has been designed to typically supply portable processor and its peripherals. Thanks to the multiple output voltages, high current capability and programmable start-up value, it can easily adapt to various applications.

FEATUREs
■ 2 Step-down converters
   – Vsdc1: 1 to 1.5 V with
      . 15 steps at 600 mA (I2C control available)
      . Programmable start-up value
      (1.2V by default)
   – Vsdc2: 1.8 V at 600 mA for general
      purpose usage
■ 5 Low-drop output regulators for different uses
   – Vdig: 1.0V (100mA), 1.2V, 1.5V (250 mA)
      . Can be supplied by Vsdc2 to minimize the
      voltage drop
      . Programmable start-up value
      (1.2V by default)
   – Vana1: 1.5, 1.8, 2.5, 2.8 V - 150 mA
   – Vana2: 1.8, 2.8, 3.0, 3.3 V - 150 mA
   – Vana3: 1.8, 2.8, 3.0, 3.3 V - 150 mA
   – Vmmc: 1.8, 2.5, 2.85, 3.0 V - 150mA
■ Miscellaneous
   – Vana(i) have programmable start-up output
      voltage and ON or OFF (default) status
   – 32 kHz input used for state machine
   – Processor supply monitoring
   – Processor reset control
   – Control by serial I2C interface
   – Thermal shutdown

APPLICATIONs
