K CAT3200, CAT3200-5 Low Noise Regulated Charge Pump DC-DC Converter DESCRIPTION The CAT3200 and CAT3200-5 are switched capacitor boost converters that deliver a low noise, regulated output voltage. The CAT3200-5 gives a fixed regulated 5V output. The CAT3200 has an adjustable output using external resistors. The constant frequency 2MHz charge pump allows small 1 µF ceramic capacitors to be used. Maximum output loads of up to 100mA can be supported over a wide range of input supply voltages (2.7V to 4.5V) making the device ideal for battery- powered applications. FEATURES I Constant high frequency (2MHz) operation I 100mA output current I Regulated output voltage (5V fixed CAT3200-5, Adjustable CAT3200) I Low quiescent current (1.7mA typ.) I Input voltage operation down to 2.7V I Soft start, slew rate control I Thermal overload shutdown protection I Low value external capacitors (1 µF) I Foldback current overload protection I Shutdown current less than 1 µA I CAT3200-5 in low profile (1mm thin) 6-lead SOT23 package I CAT3200 in MSOP-8 package APPLICATIONS I 3V to 5V boost conversion I White LED driver I USB On-The-Go 5V supply A shutdown control input allows the device to be placed in power-down mode, reducing the supply current to less than 1 µA. In the event of short circuit or overload conditions, the device is fully protected by both foldback current limiting and thermal overload detection. In addition, a soft start, slew rate control circuit limits inrush current during power-up. The CAT3200-5 is available in a 6-lead, 1mm max thin SOT23 package. The CAT3200 is available in an 8-lead MSOP package. I Local 5V supply from lower rail I Battery backup systems I Handheld portable devices TYPICAL APPLICATION CAT3200-5 CNEG CPOS IN OUT ON OFF SHDN GND + - 5V Output 3.3V CAT3200 CNEG CPOS IN OUT ON OFF SHDN GND + - 3.3V VIN 5V 100mA VOUT Adjustable Output VIN FB R1 R2 100mA VOUT VOUT = 1.27 V 1+ ( R1 R2 |
