Description

The KB3361 SwitchReg is a member of Kingbor(KB) product family. It is a 1.4MHz stepdown converter with an input voltage range of 2.5V to 6.5V and output as low as 0.6V. Its low supply current, small size, and high switching frequency make the KB3361 the ideal choice for portable applications.

The KB3361 is available in either a programmable version with external feedback resistors. It can deliver up to 800mA of load current while maintai- ning a low 27µA no load quiescent current. The of external components while keeping switching losses low.

The KB3361 feedback and control delivers excel lent load regulation and transient response with a small output inductor and capacitor. The KB3361 is designed to maintain high efficiency throughout the operating range and provides fast turn-on time.

The KB3361 is available in a low profile (1.3mm) SOT23-5 package and is rated over the -40°C to +85°C temperature range. 75 The 1.4MHz switching frequency minimizes the size
