170 mA 13 V, high efficiency boost converter + LDO
  • active 活性

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 RDSonN-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 limiter, thermal shutdown and inductor peak current limit. The STOD1317B is packaged in DFN12L (3 x 3 x 0.8 mm) height.
