MAX17595/MAX17596/MAX17597

Peak-Current-Mode Controllers for

Flyback and Boost Regulators

General Description

Benefits and Features

The MAX17595–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.

● Programmable Switching Frequency Allows

Optimization of the Magnetic and Filter Components,

Resulting in Compact, Cost-Effective, Efficient

Isolated/Non-Isolated Power Supplies

• 100kHz to 1MHz Programmable Switching

Frequency with Optional Synchronization

• Peak Current Mode Control Provides Excellent

Transient Response

- Ofﬂine (Universal Input AC) and Telecom (36V to 72V)

Flyback Controller—MAX17595

- DC-DC (4.5V to 36V) Flyback Controller—

MAX17596

- Nonsynchronous (4.5V to 36V) Boost PWM

Controller—MAX17597

The MAX17595–MAX17597 house an internal error amplifier

with 1% accurate reference, eliminating the need for an

external reference. The switching frequency is programma-

ble from 100kHz to 1MHz with an accuracy of 8%, allow-

ing optimization of magnetic and filter components, resulting

in compact and cost-effective power conversion. For

EMI-sensitive applications, the MAX17595–MAX17597

family incorporates a programmable frequency dithering

scheme, enabling low-EMI spread-spectrum operation.

• 3mm x 3mm TQFN Package

● Programmable Frequency Dithering Enables Low-

EMI Spread-Spectrum Operation

● Integrated Protection Features Enhance System

Reliability

• Adjustable Current Limit with External Current-

Sense Resistor

• Fast Cycle-By-Cycle Peak Current Limiting

• Hiccup-Mode Short-Circuit Protection

• 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 compensation

scheme is provided to ensuree stability of the peak-

current-mode control scheme.

• Programmable Soft-Start and Slope Compensation

• Input Overvoltage Protection

Hiccup-mode overcurrent protection and thermal

shutdown are provided to minimize dissipation in

overcurrent and overtemperature fault conditions.

Ordering Information/Selector Guide appears at end of

data sheet.
