Description
M62291GP is an integrated circuit designed as 5 V fixed output voltage general purpose DC/DC converter.
Integrating peripheral components in ultra small 5-pin SOT23 package allows for simplified external circuit and
compact low cost design.
This IC is applicable to portable equipments due to low circuit current 570 µA (typ.)
Especially this is most suitable for localized power source such as audio equipments, and so on as converter from 12 to
5 V system.
Features
• Wide operation power supply voltage range…….. 6 V to 15 V (V_CC = 12 V typ.)
• Low power consumption……………………...…. 570 µA max. (V_CC = 12 V typ., at no load)
• Built-in oscillator without peripheral components (120 kHz typ.)
• Built-in over current protection circuit
• Ultra small 5-pin SOT23 package
Applications
Localized power supply for audio, portable equipments, and general electric products
