ETA1136
ETA1136 is Fixed 5V/1.5A Output Synchronous Boost manufactured by ETA.
DESCRIPTION
The ETA1136 is a high efficiency synchronous step-up converter that can provide up to 1.5A to a fixed 5V output from a low voltage source. Unlike most step-up converter, it incorporates circuits that disconnect the input from output, during shutdown, short-circuit, output current overloading, or other events when output is higher than the input. This eliminates the need for an external MOSFET and its control circuitry to disconnect the input from output, and provides robust output overload protection.
FEATURES
- Output Disconnect
- Short-circuit Protection
- Fixed 5V/1.5A Output Power
- Output to Input Reversed Current Protection
- Up to 96% Efficiency
- 40μA No load IQ and light load PFM Mode
- Internal Synchronous Rectifier
- Current Mode control
- Logic Control Shutdown and Thermal shutdown
- SOT23-5 Package
A switching frequency of 1MHz minimizes solution footprint by allowing the use of tiny and low profile inductors and ceramic capacitors. An internal synchronous MOSFET provides highest efficiency and with a current mode control that is internally pensated, external parts count is reduced to minimal.
ETA1136 is housed in a tiny SOT23-5 package.
APPLICATIONS
- USB OTG for MIDs, Smartphones
- Mobile back-up Battery Chargers
- Alkaline, Ni Cd, and Ni Mh batteries applications
- USB powered devices
