Overview
CURRENT MODE PWM CONTROLLER General Description The AZ2842/3/4/5 are high performance fixed frequency current-mode PWM controller series.
w w w 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.
The AZ2842 and AZ2844 have UVLO thresholds of 15.
5V(on) and 10...
