Data Sheet  
CURRENT MODE PWM CONTROLLER  
AZ3842A/3A/4A/5A  
General Description  
Features  
The AZ3842A/3A/4A/5A are high performance fixed  
frequency current-mode PWM controller series. They  
are improved versions of AZ3842/3/4/5.  
·
Low Start-up Current: 0.15mA  
Robust V Line/Load Regulation  
·
REF  
Low Line Regulation : 4mV  
Low Load Regulation : 4mV  
High Stability of Reference Voltage over a Full  
These integrated circuits are optimized for off-line and  
DC-DC converter applications with minimum external  
components. They feature under-voltage lockout  
(UVLO) circuit with low start-up current, trimmed  
oscillator for precise duty cycle control, current sense  
comparator providing maximum current limiting and a  
totem pole output stage for increasing output current.  
In addition, these ICs also feature accurate protection  
against over-temperature, over-current and maximal  
output power.  
·
o
Temperature Range: 0.2mV/ C  
·
·
Operating Frequency up to 500KHz  
High PWM Frequency Stability over a Full Tem-  
perature Range: 2.5%  
High PWM Frequency Stability under a Full Sup-  
ply Voltage Range: 0.2%  
Accurate Over-temperature Protection with Hys-  
teresis  
UVLO with Hysteresis  
·
·
·
The AZ3842A and AZ3844A have UVLO thresholds  
of 16V(on) and 10V(off); The corresponding thresh-  
olds for AZ3843A and AZ3845A are 8.4 V(on) and  
7.6V(off).  
Applications  
·
·
·
·
·
·
Off-line Converter  
DC-DC Converter  
Voltage Adapter  
CRT Monitor Power Supply  
Desktop Power Supply  
DVD/STB Power Supply  
The AZ3842A and AZ3843A can operate approaching  
100% duty cycle; AZ3844A and AZ3845A can operate  
from zero to 50% duty cycle.  
These ICs are available in 3 packages: SOIC-8, DIP-8  
and SOIC-14.
