MIC4680 - 1A 200kHz SuperSwitcher Buck Regulator Final Information

Datasheet Summary

Description

The MIC4680 SuperSwitcher™ is an easy-to-use fixed or adjustable output voltage step-down (buck) switch-mode voltage regulator.

The 200kHz MIC4680 achieves up to 1.3A of continuous output current over a wide input range in a 8-lead SOP (small outline package).

Features

SO-8 package with up to 1.3A output current All surface mount solution Only 4 external components required Fixed 200kHz operation 3.3V, 5V, and adjustable output versions Internally compensated with fast transient response Wide 4V to 34V operating input voltage range Less than 2µA typical shutdown-mode current Up to 90% efficiency Thermal shutdown Overcurrent protection.

MIC4680 Micrel MIC4680 1A 200kHz SuperSwitcher™ Buck Regulator Final Information General Description The MIC4680 SuperSwitcher™ is an easy-to-use fixed or adjustable output voltage step-down (buck) switch-mode voltage regulator. The 200kHz MIC4680 achieves up to 1.3A of continuous output current over a wide input range in a 8-lead SOP (small outline package). The MIC4680 is available in 3.3V and 5V fixed output versions or adjustable output down to 1.25V. The MIC4680 has an input voltage range of 4V to 34V, with excellent line, load, and transient response. The regulator performs cycle-by-cycle current limiting and thermal shutdown for protection under fault conditions. In shutdown mode, the regulator draws less than 2µA of standby current.
