The controller drives an external transistor (Transistor Driver output) and supports a single output phase, with output configuration positive and isolation-capable. The 69% maximum duty cycle defines the voltage conversion ratio achievable in flyback topology. ## Switching frequency and control flexibility Switching frequency is programmable from 50kHz to 250kHz via the Frequency Control pin — a lower frequency reduces switching losses but requires larger magnetics; higher frequency shrinks the transformer at the cost of increased FET switching loss. The controller lacks clock synchronization (No), so it cannot be slaved to an external system clock for noise management. Control features include Current Limit, Enable, Frequency Control, and Soft Start. Soft Start limits inrush current during startup, critical when charging the output capacitor of an isolated supply. The Enable pin allows the supply to be sequenced on/off from a logic signal. ## Package and thermal environment Housed in a 16-WFQFN Exposed Pad package (3x3mm, 16-TQFN supplier package), surface-mount mounting. Available in Tape & Reel (TR) or Cut Tape (CT) for prototyping or production volume. The part is RoHS3 compliant. ## Sourcing and compliance RoHS3 compliant per the lifecycle record.","metaTitle":"MAX17690ATE+T Flyback Controller, 4.5-60V, 16-TQFN","metaDescription":"Active Analog Devices MAX17690ATE+T flyback controller, 4.5-60V supply, 50-250kHz switching, -40 to 125°C, 16-TQFN.
