Data Sheets:
The MIC2298 is a high power boost-switching regulator that is optimized for constant-current control. The MIC2298 is capable of driving up to two series 1A white LED for photoflash, flashlight and other applications. The feedback voltage is only 200mV, minimizing ballast power dissipa-tion in constant-current control applications for improved operating efficiency.
The MIC2298 has a brightness pin that allows for a programmable torch mode as well full flash with a single pin when driving high current LEDs.
The MIC2298 implements a constant frequency 1MHz PWM control scheme to make the smallest possible design.
The 2.5V to 10V input voltage range of MIC2298 allows direct operation from 1- and 2-cell Li-Ion as well as 3- to 6-cell NiCad/NiMH/Alkaline battery sources. Maximum battery life is assured with a low 1µA shutdown current.
- 3.5A minimum switch current delivers at least 7W of output power over temperature
- 200mV ±10% feedback voltage
- 2.5V to 10V input voltage
- Output voltage up to 30V (max)
- Output over voltage protection (OVP)
- 1MHz operation
- Programmable output current
- <1% line regulation
- 1µA shutdown current
- Over-temperature protection
- Externally programmable soft-start
- Under voltage lockout (UVLO)
- -40°C to +125°C junction temperature range
