STMicroelectronics A6983I DC-DC Converter, 38V dc/ 4.5A Output, 3.5 → 38 V dc Input, 10W, Surface Mount, +150°C

The STMicroelectronics Primary output voltage can be accurately adjusted, whereas the isolated secondary output is derived by using a given transformer ratio. No optocoupler is required. The primary sink capability up to -4.5 A (even during soft-start) allows a proper energy transfer to the secondary side, as well as enables a tracked soft-start of the secondary output. The control loop is based on a peak current mode architecture and the device operates in forced PWM.
