CAT3200HU2 Low Noise Regulated Charge Pump DC-DC Converter Description The CAT3200HU2 is a switched capacitor boost converter that delivers a low noise, regulated output voltage. The CAT3200HU2 gives a fixed regulated 5 V output when the FB pin is tied to ground, otherwise it provides an adjustable output using external resistors. The constant frequency 2 MHz charge pump allows small 1 mF ceramic capacitors to be used. Maximum output loads of up to 100 mA can be supported over a wide range of i.

CAT3200HU2 Low Noise Regulated Charge Pump DC-DC Converter Description The CAT3200HU2 is a switched capacitor boost converter that delivers a low noise, regulated output voltage. The CAT3200HU2 gives a fixed regulated 5 V output when the FB pin is tied to ground, otherwise it provides an adjustable output using external resistors. The constant frequency 2 MHz charge pump allows small 1 mF ceramic capacitors to be used. Maximum output loads of up to 100 mA can be supported over a wide range of input supply voltages making the device ideal for battery−powered applications. A shutdown control input allows the device to be placed in power−down mode, reducing the supply current to less than 1 mA. 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 CAT3200HU2 is available in the tiny 8−pad UDFN 2 mm x 2 mm package. Features • Constant High Frequency (2 MHz) Operation • 100 mA Output Current • Regulated Output Voltage (5 V Fixed or Adjustable) • Low Quiescent Current (1.7 mA Typ.) • Soft Start, Slew Rate Control • Reverse Leakage Protection • Thermal Overload Shutdown Protection • Low Value External Capacitors (1 mF) • Foldback Current Overload Protection • Shutdown Current less than 1 mA • 8−pad UDFN 2 mm x 2 mm Package • These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant Typical Applications • 3 V to 5 V Boost Conversion • 2.5 V to 3.3 V Boost Conversion • White LED Driver • Handheld Portable Devices http://onsemi.com UDFN−8 HU2 SUFFIX CASE 517AW MARKING DIAGRAM CAX YM CA = Product Name X = Assembly Location Y = Production Year (Last Digit) M = Production Month (1−9, O, N, D) PIN CONNECTIONS CPOS VIN CNEG PGND 1 (Top View) VOUT FB SHDN SGND ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 2 of this data sheet. © Semiconductor Components Industries, LLC, 2014 1 September, 2014 − Rev. 5 Publication Order Number: CAT3200HU2/D 5 V Output 1 mF VIN 3.3 V CNEG CPOS IN OUT CAT3200HU2 ON OFF SHDN FB SGND PGND 1 mF VOUT = 5 V CAT3200HU2 5V VOUT 100 mA 1 mF Adjustable Output 1 mF VIN 3.3 V ON OFF 1 mF CNEG CPOS IN OUT CAT3200HU2 SHDN FB SGND PGND VOUT 100 mA R1 1 mF R2 ǒ Ǔ VOUT + 1.27 V 1 ) R1 R2 Figure 1.
