AC-DC switching power supply control IC with standby mode

I
Overview
The AN8027 and AN8037 are ICs developed for self-
excited switching regulator of RCC local resonance con-
trol type.
These ICs are designed to achieve stability and high
efficiency over a wide input voltage range and loads range
(light loads to heavy loads), for supporting input levels
used worldwide and improved conformance with energy
conservation laws.
I
Features
Support improved conformance with energy conserva-
tion laws by providing two operating modes.
Standby mode (light loads):
Achieves better efficiency due to reduced frequency .
Normal mode:
Achieves high efficiency in RCC local resonance op-
eration with zero-cross detection.
Incorporating an input voltage compensation function available to a wide input range for worldwide use.
This function compensates the maximum on-period in inverse proportion to the input voltage.
Incorporating a timer latch function.
The time period can be adjusted according to the overload in normal mode or standby mode.
This function makes it possible to protect the IC from damage that may be caused by the short-circuiting of the IC's
external capacitor for the timer.
Incorporating an overvoltage protection function. (detects at V
CC
pin)
Incorporating a pulse-by-pulse overcurrent protection function, which makes latch protection possible at the time of
the short-circuiting of the transformer's primary winding.
Adopting a 9-pin single inline package (E-9S: available to manufacturing in overseas).
AN8027: Transformer resetting is detected from the high- or low-level signal on the TR pin.
AN8037: Transformer resetting is detected from the falling edge of the high-level signal on the TR pin.
Refer to the "[1] operation descriptions 7. local resonance operation" section in the application notes.
