General Description  
Benefits and Features  
The MAX17598/MAX17599 low I , active clamp current-  
Q
S Active Clamp, Peak Current-Mode Forward PWM  
mode PWM controllers contain all the control circuitry  
required for the design of wide-input isolated/non-iso-  
lated forward-converter industrial power supplies. The  
MAX17598 is well-suited for universal input (rectified 85V  
AC to 265V AC) or telecom (36V DC to 72V DC) power  
supplies. The MAX17599 is optimized for low-voltage  
industrial supplies (4.5V DC to 36V DC).  
Controller  
S 20FA Startup Current in UVLO  
S 4.5V to 36V Input-Supply Operating Range  
(MAX17599)  
S Programmable Input Undervoltage Lockout  
S Programmable Input Overvoltage Protection  
The devices include an AUX driver that drives an aux-  
iliary MOSFET (clamp switch) that helps implement the  
active-clamp transformer reset topology for forward con-  
verters. Such a reset topology has several advantages  
including reduced voltage stress on the switches, trans-  
former size reduction due to larger allowable flux swing,  
and improved efficiency due to elimination of dissipative  
snubber circuitry. Programmable dead time between the  
AUX and main driver allows for zero voltage switching (ZVS).  
S Programmable 100kHz to 1MHz Switching  
Frequency  
S Switching Frequency Synchronization  
S Programmable Frequency Dithering for Low EMI  
Spread-Spectrum Operation  
S Programmable Dead Time  
S Adjustable Soft-Start  
S Programmable Slope Compensation  
The switching frequency is programmable from 100kHz  
to 1MHz for the devices with an accuracy of Q5% using  
an external resistor. This allows the optimization of the  
magnetic and filter components, resulting in compact,  
cost-effective isolated/nonisolated power supplies. For  
EMI-sensitive design, the ICs incorporate a program-  
mable frequency dithering feature and enables low EMI  
spread-spectrum operation.  
S Fast Cycle-by-Cycle Peak-Current-Limit 40ns  
Typical Propagation Delay  
S 70ns Internal Leading-Edge Current-Sense

S Hiccup Mode Output Short-Circuit Protection  
S Soft-Stop for Well-Controlled Clamp Capacitor  
Discharge  
An input undervoltage lockout (EN/UVLO) is provided  
for programming the input-supply start voltage, and to  
ensure proper operation during brownout conditions. The  
EN/UVLO input is also used to turn on/off the ICs. Input  
overvoltage (OVI) protection scheme is provided to make  
sure that the regulator shuts down when the input supply  
exceeds its maximum allowed value.  
S Negative Current Limit to Limit Clamp-Switch  
Clamp Capacitor and Transformer Reverse Current  
S 3mm x 3mm, Lead-Free 16-Pin TQFN  
Applications  
Telecom and Datacom Power Supplies  
Isolated Battery Chargers  
To control inrush current, the devices incorporate an SS  
pin to set the soft-start time for the regulator. Power dis-  
sipation under fault conditions is minimized by a hiccup  
overcurrent protection (hiccup mode). A soft-stop feature  
provides safe discharging of the clamp capacitor when the  
device is turned off, and allows the controller to restart in a  
well-controlled manner. Additionally, a negative current limit  
is provided in the current-sense circuitry, helping limit the  
clamp switch current under dynamic operating conditions.

A SYNC feature is provided to synchronize multiple convert-  
ers to a common external clock in noise-sensitive applica-  
tions. Overtemperature faults trigger a thermal shutdown for  
reliable protection of the device. The ICs are available in a  
16-pin, TQFN package with 0.5 mm lead spacing.
