TS3420 2A, 1.25MHz Synchronous Buck Converter SOT-26 Pin Definition: 1. EN 2. Ground 3. Switching Output 4. Input 5. Ground 6. Feedback General Description TS3420 is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. The device is available in an adjustable version. Supply current with no load is 200uA and drops to <1uA in shutdown. The 2.8V to 5.5V input voltage range makes TS3420 ideally suited for single Li-Ion, two to three AA battery-powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems. Switching frequency is internally set at 1.25MHz, allowing the use of small surface mount inductors and capacitors.
