The LM34966-Q1 is a wide input range, non-synchronous boost controller that uses peak current mode control. The device can be used in boost, SEPIC, and flyback topologies. The device can start up from a 1-cell battery with a minimum of 2.97 V if the BIAS pin is connected to the VCC pin. It can operate with the input supply voltage as low as 1.5 V if the BIAS pin is greater than 3.5 V. The internal VCC regulator also supports BIAS pin operation up to 40 V (45-V absolute maximum) for automotive load dump. The switching frequency is dynamically programmable with an external resistor from 100 kHz to 500 kHz. https://elecena.pl/product/30543410/500-khz-wide-vin-nonsynchronous-boost-flyback-sepic-controller-pwp-14-40-to-150 2026-07-31 https://elecena.pl/product/30543410/500-khz-wide-vin-nonsynchronous-boost-flyback-sepic-controller-pwp-14-40-to-150 2026-10-06
