# TPS61023DRLR (Component) ## Description 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 ## Component Details - **Owner:** lcsc - **Created:** 11/5/2024 - **Last Updated:** 6/6/2026 - **Visibility:** Public - **Max Input Voltage:** 500mV~5.5V - **Frequency:** 1MHz - **License:** https://creativecommons.org/licenses/by/4.0/ - **Datasheet URL:** https://www.ti.com/lit/ds/symlink/tps61023.pdf?HQS=dis-dk-null-digikeymode-dsf-pf-null-wwe&ts=1780366470639&ref_url=https%253A%252F%252Fwww.icbanq.com%252F - **Manufacturer Name:** TI(德州仪器) - **Symbol Style:** parametric-v1 - **Package or Case Code:** SOT-563_L1.6-W1.2-P0.50-LS1.6-BR - **LCSC Part Number:** C919459 - **Output Current:** 3A - **JLCPCB Part Class:** Extended Part - **Operating Temperature:** -40℃~+125℃@(TJ) - **Max Output Voltage:** 2.2~5.5V - **Logic Function:** Boost type - **Manufacturer Part Number:** TPS61023DRLR - **Part Type:** DC-DC Converters - **Used in:** 74 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
