Boost Switching Regulator IC Positive Adjustable 2.2V 1 Output 3A SOT-563, SOT-666 TPS61023 device is a synchronous boost converter with 0.5-V ultra-low input voltage. The device provides a power supply solution for portable equipment and smart devices powered by various batteries and super capacitors. The TPS61023 has typical 3.7-A valley switch current limit over full temperature range. With a wide input voltage range of 0.5 V to 5.5 V, the TPS61023 supports super capacitor backup power applications, which may deeply discharge the super capacitor. The TPS61023 operates at 1-MHz switching frequency when the input voltage is above 1.5 V. The switching frequency decreases gradually to 0.5 MHz when the input voltage is below 1.5 V down to 1 V. The TPS61023 enters power-save mode at light load condition to maintain high efficiency over the entire load current range. The TPS61023 consumes a 20- µA quiescent current from VOUT in light load condition. During shutdown, the TPS61023 is completely disconnected from the input power and only consumes a 0.1-µA current to achieve long battery life. The TPS61023 has 5.7-V output overvoltage protection, output short circuit protection, and thermal shutdown protection. • Input voltage range: 0.5 V to 5.5 V • 1.8-V Minimum input voltage for start-up • Output voltage setting range: 2.2 V to 5.5 V • Two 47-mΩ (LS) / 68-mΩ (HS) MOSFETs • 3.7-A Valley switching current limit • 94% Efficiency at VIN = 3.6 V, VOUT = 5 V and IOUT = 1.5 A • 1-MHz Switching frequency when VIN > 1.5 V and 0.5-MHz switching frequency when VIN < 1 V • Typical 0.1-µA shutdown current from VIN and SW • ±2.5% Reference voltage accuracy over –40°C to +125°C • Auto PFM operation mode at light load • Pass-through mode when VIN > VOUT • True disconnection between input and output during shutdown • Output overvoltage and thermal shutdown protections • Output short-circuit protection • 1.2-mm × 1.6-mm SOT563 (DRL) 6-pin package

OR Controller N+1 ORing Controller N-Channel N:1 6-DFN (2x3) The LTC®4359 is a positive high voltage ideal diode controller that drives an external N-channel MOSFET to replace a Schottky diode. It controls the forward-voltage drop across the MOSFET to ensure smooth current delivery without oscillation even at light loads. If a power source fails or is shorted, a fast turn-off minimizes reverse current transients. A shutdown mode is available to reduce the quiescent current to 9μA for load switch and 14µA for ideal diode applications. When used in high current diode applications, the LTC4359 reduces power consumption, heat dissipation, voltage loss and PC board area. With its wide operating voltage range, the ability to withstand reverse input voltage, and high temperature rating, the LTC4359 satisfies the demanding requirements of both automotive and telecom applications.
