| Part Number | Description |
|---|---|
| SC1101 | Asynchronous Voltage Mode PWM Controller |
| SC1102 | Synchronous Voltage Mode Controller |
| SC1102A | Synchronous Voltage Mode Controller |
| SC1104A | (SC1104A/B) Synchronous Voltage Mode PWM Controller |

The SC1103 is a versatile, low-cost, voltage-mode PWM controller designed for 12V input DC/DC power supply applications. A simple, fixed-voltage buck regulator can be implemented using the SC1103 with a minimum of external ponents. Internal level shift and drive circuitry eliminates the need for an expensive p-channel, high-side switch.
