MAX17595/MAX17596/MAX17597

Peak-Current-Mode Controllers for

Flyback and Boost Regulators

General Description

Benefits and Features

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 con-

verter. 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 ref-

erence, 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, result-

ing in compact and cost-effective power conversion. For

EMI-sensitive applications, the MAX17595/MAX17596/

MAX17597 family incorporates a programmable frequen-

cy dithering scheme, enabling low-EMI spread-spectrum

operation.

Frequency with Optional Synchronization

S Programmable Frequency Dithering for Low-EMI

Spread-Spectrum Operation

S Adjustable Current Limit with External Current-

Sense Resistor

S Fast Cycle-By-Cycle Peak Current Limiting

S Hiccup-Mode Short-Circuit Protection

S Overtemperature Protection

Users can start the power supply precisely at the desired

input voltage, implement input overvoltage protection, and

program soft-start time. A programmable slope com-

pensation scheme is provided to ensuree stability of the

peak-current-mode control scheme.

S Programmable Soft-Start and Slope Compensation

S Input Overvoltage Protection

S Space-Saving, 3mm x 3mm TQFN Package

Hiccup-mode overcurrent protection and thermal

shutdown are provided to minimize dissipation in

overcurrent and overtemperature fault conditions.
