LD7535/LD7535A
12/11/2007
Green-Mode PWM Controller with Integrated Protections
Rev. 01c
General Description
The LD7535/LD7535A are low cost, low startup current,
current mode PWM controllers with green-mode power-
saving operation. The integrated functions include the
leading-edge blanking of the current sensing, internal slope
compensation and the tiny package of SOT-26. They
provide the users a superior AC/DC power application of
higher efficiency, low external component counts, and lower
cost solution.
Furthermore, LD7535/LD7535A features more protections
like OLP (Over Load Protection) and OVP (Over Voltage
Protection) to eliminate the external protection circuits. And
to satisfy different designs, 2 versions of OVP levels are
implemented as ---
z LD7535 --- 28.0V ± 1.5V.
z LD7535A --- 21.0V ± 1.5V.
Features
z High-Voltage CMOS Process with Excellent ESD
protection
z Very Low Startup Current (<20μA)
z Current Mode Control
z Non-audible-noise Green Mode Control
z UVLO (Under Voltage Lockout)
z LEB (Leading-Edge Blanking) on CS Pin
z Programmable Switching Frequency
z Internal Slope Compensation
z OVP (Over Voltage Protection) on Vcc Pin
z OLP (Over Load Protection)
z 300mA Driving Capability
Applications
z Switching AC/DC Adaptor and Battery Charger
z Open Frame Switching Power Supply
z 384X Replacement
Typical Application
