Description
M62293FP is 3.3 V and 2.5 V 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 8-pin package.
The IC also has Reset circuit with time delay that monitors power supply (V_CC = 5 V) and one regulator output (Vout1
= 3.3 V; IN1 terminal), therefore an application system is protected system errors.
Especially this is most suitable for application system with microprocessor and ASIC.
Features
• 3.3 V and 2.5 V step-down converter
• 4 to 15 V wide input supply voltage (V_CC = 5 V typ.)
• Reset circuit with time delay monitors
• Supply voltage (V_CC = 5 V) and regulator output (3.3 V)
• 110 kHz fixed frequency oscillator without peripheral devices
• 8-pin SOP package
