DC-DC converter ICs are available in step-up, step-down, and inverting types. It supplies highly efficient and highly accurate output over a wide input voltage range. MM3333 is a step-up DC-DC converter with PWM / PFM automatic switching function. A step-up DC-DC converter can be configured by using only external coils, capacitors, and diodes. The small package and low current consumption make it ideal for mobile device applications that require high efficiency. In addition, the PWM / PFM automatic switching function prevents the efficiency from decreasing due to the current consumption of the IC when the load is light.
MM3333 features :
- No need external resistors (buit-in feedback resistors)
- Achieves high efficiency with low current consumption and PFM operation
- Small SOT-26B package
MM3333 applications :
- Mobile devices
- Power supply for microcomputer
