Product Summary
The AP3842CMTR-E1 is a current mode pwm controller. The AP3842CMTR-E1 is optimized for off-line and DC-DC converter applications with minimum external components. The AP3842CMTR-E1 features 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, the AP3842CMTR-E1 also feature accurate protection against over-temperature, over-current and maximal output power.
