Additional Details

The MAX17595/MAX17596/MAX17597 is a family of peak-current-mode controllers for design of wide input-voltage flyback and boost regulators. The MAX17595 offers optimized input thresholds for universal input AC-DC converters and telecom DC-DC (36V to 72V input range) power supplies. The MAX17596/MAX17597 offer input thresholds suitable for low-voltage DC-DC applications (4.5V to 36V). The MAX17597 implements a boost converter. All three controllers contain a built-in gate driver for external n-channel MOSFETs.

The MAX17595/MAX17596/MAX17597 house an internal error amplifier with 1% accurate reference, eliminating the need for an external reference. The switching frequency is programmable from 100kHz to 1MHz with an accuracy of 8%, allowing optimization of magnetic and filter components, resulting in compact and cost-effective power conversion. For EMI-sensitive applications, the MAX17595/MAX17596/MAX17597 family incorporates a programmable frequency dithering scheme, enabling low-EMI spread-spectrum operation.

Users can start the power supply precisely at the desired input voltage, implement input overvoltage protection, and program soft-start time. A programmable slope compensation scheme is provided to ensuree stability of the peak-current-mode control scheme.

Hiccup-mode overcurrent protection and thermal shutdown are provided to minimize dissipation in overcurrent and overtemperature fault conditions.

Product Detail

The MAX17595 evaluation kit (EV kit) is a fully assembled and tested circuit board that contains MAX17595 peak-current-mode controller for a flyback regulator. The EV kit is configured for an isolated 15V DC output voltage that can supply up to 1.5A current. The line input voltage range is from 85V AC to 265V AC or 120V DC to 375V DC.

The EV kit demonstrates low quiescent current and efficiency up to 86%. This high efficiency is achieved by using a single-transistor (MOSFET) flyback converter topology that operates at 120kHz switching frequency. The surface-mount transformer has a tertiary winding to power the IC after startup. An optocoupler, along with the transformer, provides galvanic isolation up to 3500V_RMS.

Warning: The EV kit is designed to operate with high voltages. Dangerous voltages are present on this EV kit and on equipment connected to it. Users who power up this EV kit or the power sources connected to it must be careful to follow safety procedures appropriately to work with high-voltage electrical equipment.

Under severe fault or failure conditions, this EV kit may dissipate large amounts of power, which could result in the mechanical ejection of a component or of component debris at high velocity. Operate this EV kit with care to avoid possible personal injury.
