LV5990M-TLM-H Datasheet, PDF (1/6 Pages) ON Semiconductor – Step-down Switching Regulator

Ordering number : ENA1849
LV5990M
Bi-CMOS IC
Low power consumption and high efficiency
Step-down Switching Regulator
Overview
LV5990M is 1ch DC-DC converter with built-in power Pch MOS transistor. The recommended operating range is 4.5V to
18V. The maximum current is 3A. The operating current is about 90μA, and low power consumption is achieved.
Functions
• 1ch SBD rectification DC-DC converter IC with built-in power Pch MOS transistor
• Maximum value of light load mode current is 90μA.
• Built-in OCP circuit with P-by-P method
• When P-by-P is generated continuously, it shifts to the HICCUP operation.
• If connect C-HICCUP to GND pin, then latch-off when over current.
• The oscillatory frequency is 360kHz.
• UVLO and built-in TSD
