M62292FP
3.3V, 1.8V FIXED 2-OUTPUT VOLTAGE DC-DC CONVERTER
DESCRIPTION
M62293FP is 3.3V and 1.8V fixed stable 2-output step-down DC-DC
converter.
It is possible to simplify peripheral circuit and to design compact and low cost
sets because this device includes peripheral devices 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),
therefore an application system is protected system errors.
Especially this is most suitable for application sysytem with microprocessor
and ASIC.
