LT8709 400kHz, Negative Buck-Boost Converter Generates a –24V/2.5A Output from a –15V to –30V Input

The LT®8709 is a synchronous PWM controller for negativeto- negative or negative-to-positive DC/DC conversion, with rail-to-rail output current monitor and control. The LT8709 is ideal for many local power supply designs. It can be easily configured in buck, boost, buck-boost, and inverting topologies with negative input voltages.
