EM8564A
HV Start-up Green-mode PWM Convertor with Brown-Out Protection
General Description
EM8564A is a high performance, low cost, HV
Start-up, current mode PWM controller with green
mode power saving. The EM8564A integrates
functions of Soft Start (SS), Under Voltage Lockout
(UVLO), Leading Edge Blanking (LEB), internal Over
Temperature Protection (OTP), and internal slope
compensation. The EM8564A also features more
protection like Over Load Protection (OLP) and
Over Voltage Protection (OVP) to prevent circuit
damage occurred under abnormal conditions. The
EM8564A also has line under-voltage protection
(Brown-out Protection).

Note 1. Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the device. These are for
stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended
periods may remain possibility to affect device reliability.
Note 2. θJA is measured in the natural convection at TA=25oC on a 4-layers high effective thermal conductivity test board with
minimum copper area of JEDEC 51-7 thermal measurement standard. The case point of θJC is on the expose pad for
PDIP-7 package.
Note 3. Devices are ESD sensitive. Handling precaution is recommended.
Note 4. The device is not guaranteed to function outside its operating conditions.
Note 5. Guaranteed by design.
