UCN datasheet – ti UC, Current-mode PWM Controller
uc3844n Devices with higher turnon or turnoff uc3844n are ideal choices for uc3844n power supplies, while the devices with a narrower hysteresis range are suited for DC-DC applications. Temperature stability, sometimes referred to as average temperature coefficient, is described by the equation: Add to Watch list. The corresponding thresholds for the UC and UC are 8.
Internally implemented circuits include under-voltage lockout featuring start up current less than 1mA, a precision reference trimmed for accuracy uc3844n the error amp input, logic to insure latched operation, a PWM comparator which also provides current limit control, and a totem pole output stage uc3844n to source or uc3844n high peak current.
