This IC converts a positive input voltage into a regulated negative output voltage. This DC-DC converter Features an On/Off function with an active low control. The internal voltage reference provides a stable output voltage which can be set from -0.5 to -12.5 V. The thermal protection feature provides oscillator shutdown in the event of an overload condition. The wide input voltage range of 2.5 to 15 V and a 60 m A output current capability allow flexible operation in a large number of applications. The TK11830 is available in a miniature SOT-23L surface mount package. Optimized Toko inductors are available.
