com RC4190 Micropower Switching Regulator Features • • • • • High efficiency – 85% typical Low quiescent current – 215 mA Adjustable output – 1.
3V to 30V High switch current – 200 mA Bandgap reference – 1.
31V • • • • • Accurate oscillator frequency – ±10% Remote shutdown capability Low battery detection circuitry Low component count 8-lead packages including small outline (SO-8) Description The RC4190 monolithic IC is a low power switch mode regulator intended for miniature power supply applications.
This DC-to-DC converter IC provides all of the active components needed to create supplies for micropower circuits (load power up to 400 mW, or up to 10W with an external power transistor).
Contained internally are an oscillator, switch, reference, comparator, and logic, plus a discharged battery detection circuit.
Application areas include on-card circuits where a non-standard voltage supply is needed, or in battery operated instrum...
