FEATURES  
DESCRIPTION  
User Programmable Soft Start With  
Active Low Shutdown  
The UCC3809 family of BCDMOS economy low power integrated circuits  
contains all the control and drive circuitry required for off-line and isolated  
DC-to-DC fixed frequency current mode switching power supplies with  
minimal external parts count. Internally implemented circuits include  
undervoltage lockout featuring startup current less than 100µA, a user ac-  
cessible voltage reference, logic to ensure latched operation, a PWM com-  
parator, and a totem pole output stage to sink or source peak current. The  
output stage, suitable for driving N-Channel MOSFETs, is low in the off  
state.  
User Programmable Maximum Duty  
Cycle  
Accessible 5V Reference  
Undervoltage Lockout  
Operation to 1MHz  
0.4A Source/0.8A Sink FET Driver  
Low 100µA Startup Current  
Oscillator frequency and maximum duty cycle are programmed with two  
resistors and a capacitor. The UCC3809 family also features full cycle soft  
start.  
The family has UVLO thresholds and hysteresis levels for off-line and  
DC-to-DC systems as shown in the table to the left.

The UCC3809 and the UCC2809 are offered in the 8 pin SOIC (D), PDIP  
(N), TSSOP (PW), and MSOP (P) packages. The small TSSOP and  
MSOP packages make the device ideal for applications where board  
space and height are at a premium.
