GENERAL DESCRIPTION
DP2358 is a high performance current mode PWM
power switch for offline flyback converter
applications.
In DP2358, PWM switching frequency with
shuffling is fixed to 65KHz and is trimmed to tight
range. The IC has built-in green and burst mode
control for light and zero loadings, which can
achieve less than 75mW standby power.
DP2358 integrates functions and protections of
Under Voltage Lockout (UVLO), VDD over
Voltage Protection (VDD OVP), Cycle-by-cycle
Current Limiting (OCP), Over Load Protection
(OLP), On-Chip Thermal Shutdown (OTP), Soft
Start, VDD Clamping and CS Pin Float Protection,
etc.

I/O Description
-- Un-connection Pin. Left float in the practical design
P IC power supply pin
Feedback pin. The loop regulation is achieved by connecting a
I photo-coupler to this pin. PWM duty cycle is determined by this
pin voltage and the current sense signal at Pin 4
I Current Sense Input Pin
O The Power MOSFET Drain
P The Ground of the IC
