Product overview
Description
The DCP3601I is a device specifically designed for an isolated buck topology.
The extended input range from 3.3 V to 36 V makes the device suitable for a wide range of industrial applications.
The 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 -1.5 A (even during soft-start) allows a proper energy transfer to the secondary side as well as enabling 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. The 150 ns blanking time filters oscillations, generated by the transformer leakage inductance.
The DCP3601I operates at a fixed switching frequency of 500 kHz and embeds protections against overcurrent, overvoltage and overtemperature events. The compact SOT23-6L package and the internal compensation of the DCP3601I help minimize design complexity and size.
