1 GENERAL DESCRIPTION The SGM30 is a MicroPower switched capacitor voltage converter that delivers a regulated output. No external inductor is required for operation. The SGM30 can deliver up to 00mA to the voltage regulated output. It features very low quiescent current and high efficiency over a large portion of its load range, making this device ideal for battery-powered applications. Furthermore, the combination of few external components and small package size keeps the total converter board area to a minimum in space-restricted applications. The SGM30 uses a pulse skipping technique to provide a regulated output from a varying input supply. The SGM30 contains a thermal management circuit to protect the device under continuous output short-circuit conditions. The SGM30 has lead (Pb) free SOT23-6 package and is rated over the -40 C to +85 C temperature range.

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. CAUTION This integrated circuit can be damaged by ESD if you don t pay attention to ESD protection. SGMICRO recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
