The L6924U is a USB compatible battery charger system with integrated power switch from ST company. It is suitable for single-cell Li-Ion batteries and supports AC adapter or USB input. It supports programmable charge current, programmable charge timer, NTC or PTC thermistor interface and so on.

The A5970AD is a step down monolithic power switching regulator with a minimum switch current limit of 1.35 A so it is able to deliver up to 1 A DC current to the load depending on the application conditions. The output voltage can be set from 1.235 V to VIN.

STOD1812 is a synchronous step-up converter designed to power passive matrix OLED (PMOLED) displays, providing the pre-charge and biasing voltage of the column matrix driver. STOD1812 uses a pulsed frequency modulation (PFM) control mode technique. The high switching frequency makes it possible to reduce the value and size of the external components. This device is particularly suitable for battery-operated applications, where overall system efficiency is the major concern. Synchronous rectification has been integrated in the device in order to eliminate the external Schottky diode. An internal compensation net is also integrated, enabling the STOD1812 to provide excellent load transient performance in addition to good load regulation.

STCF06 is a high efficiency power supply solution to drive a single flash LED in camera phones, PDAs and other battery powered devices. It is a buck-boost converter able to guarantee a proper LED current control over all possible conditions of battery voltage and LED forward voltage. The output current control ensures a good current regulation over the forward voltage spread characteristics of the flash LED. All the functions can be controlled by I²C interface.

The STCS1A is a BiCMOS constant current source designed to provide a precise constant current starting from a varying input voltage source. The main target is to replace discrete components solution for driving LEDs in low voltage applications such as 5 V, 12 V or 24 V giving benefits in terms of precision, integration and reliability. The current is set with external resistor up to 1.5 A with a ± 10 % precision; a dedicated pin allows implementing PWM dimming. An external capacitor allows setting the slope for the current rise from tens of microseconds to tens of milliseconds allowing reduction of EMI. An open-drain pin output provides information on load disconnection condition.

The PM6670AS is a complete DDR2/3 power supply regulator designed to meet JEDEC specifications. It integrates a constant on-time (COT) buck controller, a 2 Apk sink/source low drop out regulator and a 15 mA low noise buffered reference. The COT architecture assures fast transient response supporting both electrolytic and ceramic output capacitors. An embedded integrator control loop compensates the DC voltage error due to the output ripple. The 2 Apk sink/source linear regulator provides a low dropout voltage of 0.35V and a high output current of 2A.
