AN8027 Overview
Voltage Regulators AN8027, AN8037 AC-DC switching power supply control IC with standby mode s Overview The AN8027 and AN8037 are ICs developed for selfexcited switching regulator of RCC local resonance control 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...
AN8027 Key Features
- Support improved conformance with energy conservation laws by providing two operating modes. 0.3 +0.1 -0.05
- Standby mode (light loads): 3.0±0.3 Achieves better efficiency due to reduced frequency
- Normal mode: SIP009-P-0000C Achieves high efficiency in RCC local resonance operation with zero-cross detection
- Incorporating an input voltage pensation function available to a wide input range for worldwide use
- This function pensates 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 ext
- Incorporating an overvoltage protection function. (detects at VCC pin)
- Incorporating a pulse-by-pulse overcurrent protection function, which makes latch protection possible at the time of the
