MIC2292/93  
High Frequency PWM White LED Drivers with  
Internal Schottky Diode and OVP  
General Description  
Features  
The MIC2292 and MIC2293 are high frequency, Pulse Width  
Modulator (PWM) boost regulators optimized for constant-  
current, white LED driver applications. Because of their  
constant PWM switching frequencies of 1.6MHz and 2MHz,  
respectively, the MIC2292/93 can use the smallest external  
components, allowing designers to avoid sensitive IF bands  
in their RF applications.  
• 2.5V to 10V input voltage  
• Output voltage up to 34V  
• Internal Schottky diode  
• 1.6MHz PWM operation (MIC2292)  
• 2.0MHz PWM operation (MIC2293)  
• Stable with ceramic capacitors  
• 15V and 34V output overvoltage protection options  
• 500mA switch current rating  
• 95mV feedback voltage  
The products feature an internal Schottky diode and two  
levels of output overvoltage protection allowing a small size  
and efficient DC/DC solution that requires only four external  
components.  
• <1% line and load regulation  
• <1µA shutdown current  
• Over-temperature protection  
• UVLO  
• 8-lead (2mm × 2mm) MLF™package  
• –40°C to +125°C junction temperature range  
The 2.5V to 10V input voltage range of MIC2292/3 allows  
direct operation from 1- and 2-cell Li Ion as well as 3- to 4-cell  
NiCad/NiMH/Alkalinebatteries.TheMIC2292/3productsare  
available in a small size 2mm × 2mm 8-lead MLF™ package  
and have a junction temperature range of –40°C to +125°C.  
All support documentation can be found on Micrel’s web  
site at www.micrel.com.  
Applications  
• White LED driver for backlighting  
– Cell phones  
– PDAs  
– GPS systems  
– Digital cameras  
– MP3 players  
– IP phones
