The STOD13AS is a 250mA dual DC-DC converter for powering AMOLED displays. It integrates a step-up and an inverting DC-DC converter making it particularly suitable for battery operated products, in which the major concern is overall system efficiency. It works in pulse skipping mode during low load conditions and PWM-MODE at 1.5MHz frequency for medium/high load conditions. The high frequency allows the value and size of external components to be reduced. The Enable pin can be used for shutdown mode. The low quiescent current enables STOD13AS to save battery power in standby mode.

The STOD1317B is a fixed frequency, high efficiency, boost DC-DC converter with cascaded LDO able to provide output voltages ranging from 6 V to 13 V starting with an input voltage from 2.6 V to 4.8 V. The device is designed to supply loads that are very sensitive to output ripple such as AMOLED display panels. A dedicated LDO is able to suppress any ripple and noise coming out from the DC-DC converter. The LDO works with a constant drop in order to maintain high efficiency in the whole operating range. The low RDSon N- channel and P-channel MOSFET switches are integrated and contribute to achieving high efficiency. The true-shutdown feature allows physical disconnection of the battery from the load when the device is in shutdown mode. The control technique is able to maintain efficiency higher than 85% at light loads and higher than 80% at full load. The device includes soft-start control, inrush current
