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 which contain all the circuitry

required for the design of wide input-voltage flyback

and boost regulators. The MAX17595 offers optimized

input rising and falling thresholds for universal input

AC-DC converters and telecom DC-DC (36V–72V input

range) power supplies. The MAX17596 offers input rising

and falling thresholds suitable for low-voltage DC-DC

applications (4.5V–36V input range). The MAX17597

offers all circuitry needed to implement a boost converter

controller. All three controllers contain a built-in gate

driver for external n-channel MOSFETs.

S Current Mode Control Provides Excellent

Transient Response

S Low 20µA Startup Supply Current

S 100kHz to 1MHz Programmable Switching

The MAX17595/MAX17596/MAX17597 house an inter-

nal error amplifier with 1% accurate reference, useful

in implementations without the need for an external

reference. The switching frequency is programmable

from 100kHz to 1MHz with an accuracy of 8% using an

external resistor, allowing optimization of magnetic and

filter components, resulting in compact and cost-effective

power conversion solutions. For EMI sensitive applica-

tions, the MAX17595/MAX17596/MAX17597 family incor-

porates a programmable-frequency dithering scheme,

enabling low-EMI spread-spectrum operation.

Spread-Spectrum Operation

S Switching Frequency Synchronization

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

An EN/UVLO input allows the user to start the

power supply precisely at the desired input voltage,

while also functioning as an on/off pin. The OVI pin

enables implementation of an input overvoltage protection

scheme, ensuring that the converter shuts down when

the DC input voltage exceeds a set maximum value. The

SS pin allows programmable soft-start time for the power

converter, and helps limit inrush current during startup.

The MAX17595/MAX17596/MAX17597 family also allows

the designer to choose between voltage soft-start and

current soft-start modes, useful in optoisolated designs.

A programmable slope compensation scheme is pro-

vided to enhance the stability of the peak-current-mode

control scheme.

Battery-Powered Applications

Industrial, Telecom, and Automotive Applications

Hiccup-mode overcurrent protection and thermal

shutdown are provided to minimize dissipation in

overcurrent and overtemperature fault conditions. The IC

is available in a space-saving 16-pin, 3mm x 3mm TQFN

package with 0.5mm lead spacing.
