DESCRIPTIONFEATURESETA1032 is highly efficient 2.5 MHz, 1.5A input current, step-up DC-to-DC converters. ETA1032 convert input voltages from 2.5 V to 5.25 V to a fixed output voltage of 5V. 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. These devices are optimized for battery-powered applications. High efficiency of up to 95% enables an extended battery life in all portable designs. Step-up operation at a switching frequency 2.5 MHz allows using 1uH inductor and 10uF output capacitor. ETA1032 is available in a CSP1.2×1.2-9 package.w   Up to 95% DC-DC Efficiencyw   Up to 1. 5A Max input currentw   Output Disconnectw   Short-circuit Protectionw   Output to Input Reversed Current Protectionw   45μA No load IQ and light load PFM Mode; BYPASS MODEw   Current Mode controlw   Logic Control Shutdown and Thermal shutdownw   Fixed 5V Output Voltagew   CSP1.2×1.2-9 package APPLICATIONSw   NFC for POS terminalw   NFC for Smart Phonew   Application with 5V Output for General Purpose
