RC4190
Features - - - - - High efficiency - 85% typical Low quiescent current - 215 m A Adjustable output - 1.3V to 30V High switch current - 200 m A Bandgap reference - 1.31V - - - - - Accurate oscillator frequency - ±10% Remote shutdown capability Low battery detection circuitry Low ponent 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 ponents needed to create supplies for micropower circuits (load power up to 400 m W, or up to 10W with an external power transistor). Contained internally are an oscillator, switch, reference, parator, 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 instruments where an RC4190 can be used to extend battery lifetime. These regulators can achieve up to 85%...
