Mini boost Buck DC Board 1.8-5V to 3.3V XA2320B (up to 150mA)

Ultra-compact DC-DC Boost/Buck converter module based on the XA2320B regulator, capable of stepping input voltages from 1.8 to 5 V up to a stable 3.3 V output with a maximum current of 150 mA. This inductor-less module is ideal for embedded applications requiring low power consumption and a small footprint.

Specifications

• Input voltage: 1.8 to 5 V
• Output voltage: 3.3 V
• Maximum output current: 150 mA
• Fixed switching frequency: 1.2 MHz
• Low-noise operation with automatic soft-start
• Shutdown current < 1 µA
• Short-circuit protection
• No inductor required
• Dimensions: 11.5 x 9.5 mm
• SOT23-6 IC with only three external capacitors
