MAGMA High-Temperature PWM Controller
CHT-MAGMA is a high-temperature voltage-mode PWM controller with a 6–30 V input range and a constant switching frequency adjustable from 50 to 500 kHz.
It combines input feed-forward compensation, a 2.5 V reference, soft start, undervoltage lockout and a power-good comparator. External clock synchronization and a CKOUT clock output support coordinated converter operation.
