OB2358L
Current Mode PWM Power Switch Frequency Shuffling
Product Specification
GENERAL DESCRIPTION
OB2358L combines a dedicated current mode
PWM controller with a high voltage power
MOSFET. It is optimized for high performance, low
standby power, and cost effective off-line flyback
converter applications in sub 27W range.
OB2358L offers complete protection coverage
with automatic self-recovery feature including
Cycle-by-Cycle current limiting (OCP), over load
protection (OLP), over temperature protection
(OTP), over voltage protection and VDD under
voltage lockout (UVLO).
Excellent EMI
performance is achieved with On-Bright
proprietary frequency shuffling technique together
with soft switching control at the totem pole gate
drive output.
The tone energy at below 20KHZ is minimized in
the design and audio noise is eliminated during
operation.
OB2358L is offered in DIP8 package.
APPLICATIONS
Offline AC/DC flyback converter for
AC/DC adapter
PDA power supplies
Digital Cameras and Camcorder Adapter
VCR, SVR, STB, DVD&DVCD Player SMPS

Notes: 1. Maximum practical continuous power in an open frame design with sufficient drain pattern as a heat sink, at 50
ambient. Higher output power is possible with extra added heat sink or air circulation to reduce thermal resistance.
