1. Describe
The LTC®1983-3 and LTC1983ES6-5#TRPBF are inverting charge-pumped DC/DC converters that produce negative regulation output. These parts require only three tiny external capacitors to deliver up to 100mA of output current. This device can operate in open loop mode or regulate the output mode depending on the input supply voltage and output current. The LTC1983-3/LTC1983-5 have many useful features Portable applications including very low quiescent current and zero current shutdown mode programmed via the SHDN pin. The LTC1983-3/LTC1983-5 are thermally and short-circuit protected. These parts are available in a 6-pin thin (1mm) ThinSOT package
2. Features
1. Fixed Output Voltages: –3V, –5V or Low Noise VIN to –VIN Inverted Output
2. ±4% Output Voltage Accuracy
3. Low Quiescent Current: 25µA
4. 100mA Output Current Capability
5. 2.3V to 5.5V Operating Voltage Range
6. Internal 900kHz Oscillator
7. “Zero Current” Shutdown
8. Short-Circuit and Over-Temperature Protected
9. Low Profile (1mm) ThinSOTTM Package
3. Applications
1. –3V Generation in Single-Supply Systems
2. Portable Equipment
3. LCD Bias Supplies
4. GaAs FET Bias Supplies
4. Pin Configuration
5. Pin Functions
1. Pin 1: Charge Pump Input Voltage. may be between 2.3V and 5.5V. VIN should be bypassed by ≥4.7µF Low ESR capacitors as close to the pins as possible for best results.
2. Pin 2 : Regulated Output Voltage for the IC. VOUT should be bypassed with a ≥4.7µF low ESR capacitor as close as possible to the pin for best performance.
3. Pin 3 : Charge Pump Flying Capacitor Positive Terminal. This node is switched between VIN and GND .
4. Pin 4 : Charge Pump Flying Capacitor Negative Terminal. This node is switched between GND and VOUT .
5. Pin 5 : Signal and Power Ground for the 6-Pin SOT-23 package. This pin should be tied to a ground plane for best performance.
6. Pin 6 : Shutdown. Grounding this pin shuts down the IC. Tie to VIN to enable. This pin should not be pulled above the VIN voltage or below GND.
