LM5158x/LM5158x-Q1 Boost/Flyback/SEPIC ConverterTexas Instruments LM5158x/LM5158x-Q1 Boost/Flyback/SEPIC Converter is a wide input range, non-synchronous boost converter with an integrated 85V, 3.26A (LM5158/LM5158-Q1) or 85V, 1.63A (LM51581/LM51581-Q1) power switch. The device can be used in boost, SEPIC, and flyback topologies. It can start up from a single-cell battery with a minimum of 3.2V. It can operate with the input supply voltage as low as 1.5V if the BIAS pin is greater than 3.2V. The BIAS pin operates up to 60V (65V absolute maximum). The switching frequency is dynamically programmable from 100kHz to 2.2MHz with an external resistor. Switching at 2.2MHz minimizes AM band interference and allows for a small solution size and fast transient response. The device provides a selectable Dual Random Spread Spectrum to help reduce the EMI over a wide frequency range.
