The MAX17690ATE+ from Analog Devices (formerly Maxim Integrated) is a versatile DC-DC switching controller engineered for isolated flyback converter applications operating in Discontinuous Conduction Mode (DCM). This device directly senses the isolated output voltage from the primary-side flyback waveform, eliminating the need for an auxiliary winding or optocoupler for output voltage regulation.
Designed for a broad input voltage range of 4.5V to 60V, the MAX17690ATE+ offers a programmable switching frequency from 50kHz to 250kHz. Key features include an EN/UVLO pin for precise power supply turn-on/off, input overvoltage protection via the OVI pin, and a 7V internal LDO output suitable for driving various MOSFETs. With 2A/4A peak source/sink gate drive currents, it is ideal for low RDS(ON) power MOSFETs.
The controller incorporates an adjustable soft-start feature to manage inrush current during startup and provides temperature compensation for the output diode forward voltage drop. Robust hiccup-mode short-circuit protection and thermal shutdown protection are integrated for reliability. The device is housed in a compact 16-pin 3mm x 3mm TQFN package, suitable for space-constrained designs.
Applications include isolated flyback converters, wide-range DC-input isolated power supplies, and systems in industrial and telecom sectors, such as PLC I/O modules.
