The MAX1561 and MAX1599 include an internal, high-voltage, low-RDS(ON) N-channel MOSFET switch for high efficiency and maximum battery life. A single DualMode input provides a simple means of brightness adjustment and on/off control.
Drives LEDs with a regulated output voltage or current (up to 120mA) from an unregulated input supply (2.7V to 5.3V). These are complete DC-DC converters requiring only four small ceramic capacitors and no inductors. 200mV Current-Sense Threshold Reduces Power Loss.
A cost effective solution to drive an array of high brightness LEDs, using the LED driver STP16CP05. The Brightness and Color is uniform due to current regulation. High efficiency DC-DC converter. Wide Input voltage range - 5 V to 35 V.
