M62294FP
3.3V, 2.0V FIXED 2-OUTPUT VOLTAGE DC-DC CONVERTER
DESCRIPTION
M62293FP is 3.3V and 2.5V f ixed stable 2-output step-down DC-DC
conv erter.
It is possible to simplif y peripheral circuit and to design compact and low
cost sets because this dev ice includes peripheral dev ices in small size
8pin package.
The IC also has Reset circuit with time delay that monitors power
supply (Vcc=5V) and one regulator output(Vout1=3.3V;IN1 terminal),
theref ore an application system is protected system errors.
Especially this is most suitable f or application sy s y t em with
microprocessor and ASIC.
FEATURES
•3.3V and 2.0V step-down conv erter
•4 to 15V wide input supply v oltage (Vcc=5V ty p.)
•Reset circuit with time delay monitors
supply v oltage(Vcc=5V)and regulator output (3.3V)
•110kHz f ixed f requency oscillator without peripheral dev ices
•8pin SOP package
