LY9523/LY9525/LY9526/LY9527/LY9528
Current mode PWM controller with integrated high
voltage power MOSFET
LY9523/LY9525/LY9526/LY9527/LY9528
GENERAL DESCRIPTION
LY 9 5 2 3 / LY 9 5 2 5 / LY 9 5 2 6 / LY 9 5 2 7 / LY 9 5 2 8
combines a dedicated current mode PWM
controller with integr ated hig h voltag e po wer
MOSFET.
Vcc low startup current and low operating
current contribute to a reliable power on startup
DIP8-300-2.54
design with LY9523/LY9525/LY9526/LY9527/LY9528. the IC operates in Extended
‘burst mod e’ to minimize switching loss. Low
er standb y po we r and hi gh er
conve rsion efficiency is thus achieved.
LY952 3/L Y 952 5/LY95 26/LY95 27 /LY9528 o perat es in the fixed P WM freque ncy ,the
frequ ency is 65KHz.
Excellent EMI perfor mance is achieve d wi th prop riet ary fre qu e ncy hufflin g echniqu e.
Soft Start with 4mS,LY9523/LY9525/LY9526/LY9527/LY9528 offers complete
protection coverage with automatic self-recovery feature including Vcc over voltage
clamp and under voltage lockout (UVLO), over voltage protection(OLP),over current
protection (OCP).L Y9 523/L Y9 52 5/L Y952 6/ LY952 7/L Y 952 8 is offered i n DIP-8
package.
