AN8027, AN8037 AC-DC switching power supply control IC with standby mode
The document describes the AN8027 and AN8037, which are AC-DC switching power supply control ICs designed for self-excited switching regulators of the RCC (Resonant Capacitor Coupled) local resonance control type. These chips support improved conformance with energy conservation laws by providing two operating modes: a standby mode for light loads to achieve better efficiency and a normal mode for high efficiency in RCC operation.
| Supply voltage (Vcc) | 24 V max |
|---|---|
| Operating ambient temperature | -30 to +85 °C |
| Package type | 9-pin single inline package |
The AN8027 detects resetting from a high- or low-level signal on the TR pin, while the AN8037 detects it from the falling edge of the high-level signal.
These ICs are designed for use in televisions, VCRs, facsimiles, and printers.
