Ma puteti ajuta cu datasheets pentru 2 SMD-uri?. Nu am gasit cu google mare lucru. Presupun a fi integrate dar nu exclud sa fie si mosfeturi capsulate in in capsula 2x4 SOIC.Este vorba de CAT7581CA si CAT7199CA. Ar mai fi I?RP 944H (presupun ca este un mosfet)la fel nu am gasit mare lucruMultumesc

Informatii de pe net ( Neverificate )The CAT7581 is a voltage mode PWM controller designed to operate from a 4.5 V to 13.2 V supply and produce an output voltage as low as 0.8 V. This 8-pin device provides an optimal level of integration to reduce size and cost of the power supply. The CAT7581 has a fixed 300 kHz oscillator and soft-start function. The CAT7581 provides a 1.5A floating gate driver design to drive N-Channel MOSFETs in a synchronous configuration.

Asemenea informatii am gasit si eu. Foarte putine, cred ca pana la urma,(temporar) renunt la depanarea lui pana voi gasi unul la fel sa-l i-au prin comparatie sau mai multe informatii despre componentele existente.Multumesc tuturor care isi dau osteneala in a ne lumina/ajuta.
