Description

STw4410 is a power management device with

advanced features. The two Switched Mode

Power Supplies (SMPS) and the four Low Drop

Output regulators (LDO) had been designed to

use the better external components, to have the

better efficiency and the better noise rejection to

the load and line transient perturbation.

This product suits well all mobile applications

thanks to its very low consumption in sleep mode.

2 Step-down converters

– Vsdc1: 1 to 1.5 V with 15 steps at 650 mA,

– Vsdc2: 1.8 V at 600 mA for general

4 Low-drop output regulators for different uses

– Vdig: 1.0, 1.2, 1.5 - 250 mA, supplied by

– Vana1: 1.5, 1.8, 2.5, 2.8 V - 150 mA

– Vana2: 1.5, 1.8, 2.5, 2.8 V - 150 mA

– Vana3: 1.5, 1.8, 2.5, 2.8 V - 150 mA

Mass memory cards (SD/MMC/SDIO)

– Vmmc: 1.8, 2.5, 2.85, 3 V - 150mA

– Level shifters

Miscellaneous

– 32 kHz control for processor

– Processor supply monitoring

2 Step down DC/DC converter/4 LDO/MMC interface

Rev 1

The high level of the dynamic performances

allows to use the product to supply all processors

used mobile phone or in multimedia platform,

furthermore, the output voltage programming of

Vsdc1 SMPS converter allows to use this power

management unit with all actual processors.

The second SMPS has been designed with a

fixed voltage of 1.8V that can be used to supply a

wild range of external devices as memory devices

for instance.

The four LDO’s can supply all the peripheral

devices that can be used on a multimedia

platform like audio or TV out devices for example.

Vdig is a high current capability LDO and it is

supplied by the Vsdc2 SMPS to reduce the power

dissipation.

This product has also embedded MMC level

shifters and the associated LDO to be used to

address the MMC card.

Soft-start procedure had been embedded in the

device managing the internal clock and the start

of the different voltage of the DC/DC regulators.

OTG programming could be done to change the

power supply start timing to let customer the

flexibility needed in their applications. STw4410

has got an internal clock that can be used to

switch the SMPS without any external clock.

The STw4410 typical applications are imaging

processor, application processor supply solutions,

mobile phones, personal digital assistants (PDA).
