CAT661

CAT661 High Frequency 100 mA CMOS Charge Pump, Inverter/Doubler Description The CAT661 is a charge−pump voltage converter. It can invert a positive input voltage to a negative output. Only two external capacitors are needed. With a guaranteed 100 mA output current capability, the CAT661 can replace a switching regulator and its inductor. Lower EMI is achieved due to the absence of an inductor. In addition, the CAT661 can double a voltage supplied from a battery or power supply. Inputs from 2.5 V to 5.5 V will yield a doubled, 5 V to 11 V output. A Frequency Control pin (BOOST/FC) is provided to select either a high (typically 135 kHz) or low (25 kHz) internal oscillator frequency, thus allowing quiescent current vs. capacitor size trade−offs to be made. The 135 kHz frequency is selected when the FC pin is connected to V+. The operating frequency can also be adjusted with an external capacitor at the OSC pin or by driving OSC with an external clock. Both 8−pin DIP and SO packages are available. For die availability, contact ON Semiconductor marketing. The CAT661 can replace the MAX660 and the LTC660 in applications where higher oscillator frequency and smaller capacitors are needed. In addition, the CAT661 is pin compatible with the 7660/1044, offering an easy upgrade for applications with 100 mA loads.

Figure 19 shows a simple switch capacitor circuit. In position 1 capacitor C1 is charged to voltage V1. The total charge on C1 is Q1 = C1V1. When the switch moves to position 2, the input capacitor C1 is discharged to voltage V2. After discharge, the charge on C1 is Q2 = C1V2. The charge transferred is: DQ + Q1 * Q2 + C1 (V1 * V2) If the switch is cycled “F” times per second, the current (charge transfer per unit time) is: I+F DQ + F C1 (V1 * V2) Rearranging in terms of impedance: I+ (V1 * V2) + V1 * V2 REQ (1 FC1) The 1/FC1 term can be modeled as an equivalent impedance REQ. A simple equivalent circuit is shown in V1 C2 V2 Figure 20. This circuit does not include the switch resistance nor does it include output voltage ripple. It does allow one to understand the switch−capacitor topology and make prudent engineering tradeoffs. For example, power conversion efficiency is set by the output impedance, which consists of REQ and switch resistance. As switching frequency is decreased, REQ, the 1/FC1 term, will dominate the output impedance, causing higher voltage losses and decreased efficiency. As the frequency is increased quiescent current increases. At high frequency this current becomes significant and the power efficiency degrades. The oscillator is designed to operate where voltage losses are a minimum. With external 150 mF capacitors, the internal switch resistances and the Equivalent Series Resistance (ESR) of the external capacitors determine the effective output impedance. A block diagram of the CAT661 is shown in Figure 21. REQ V1 V2 C1 RL REQ + 1 FC1 C2 RL Figure 19. Switched−Capacitor Building Block Figure 20. Switched−Capacitor Equivalent Circuit http://onsemi.com 7 CAT661 Oscillator Frequency Control The switching frequency can be raised, lowered or driven from an external source. Figure 22 shows a functional diagram of the oscillator circuit. The CAT661 oscillator has four control modes: Table 4. BOOST/FC Pin Connection Open BOOST/FC = V+ Open or BOOST/FC = V+ Open OSC Pin Connection Open Open External Capacitor External Clock Nominal Oscillator Frequency 25 kHz 135 kHz − Frequency of external clock If BOOST/FC and OSC are left floating (Open), the nominal oscillator frequency is 25 kHz. The pump frequency is one−half the oscillator frequency. V+ (8) By connecting the BOOST/FC pin to V+, the charge and discharge currents are increased, and the frequency is increased by approximately 6 times. Increasing the frequency will decrease the output impedance and ripple currents. This can be an advantage at high load currents. Increasing the frequency raises quiescent current but allows smaller capacitance values for C1 and C2. If pin 7, OSC, is loaded with an external capacitor the frequency is lowered. By using the BOOST/FC pin and an external capacitor at OSC, the operating frequency can be set. Note that the frequency appearing at CAP+ or CAP− is one−half that of the oscillator. Driving the CAT661 from an external frequency source can be easily achieved by driving Pin 7 and leaving the BOOST pin open, as shown in Figure 22. The output current from Pin 7 is small, typically 1 mA to 8 mA, so a CMOS can drive the OSC pin. For 5 V applications, a TTL logic gate can be used if an external 100 kΩ pull−up resistor is used as shown in Figure 23.

CAT661 Block Diagram http://onsemi.com 8 CAT661 Capacitor Selection Low ESR capacitors are necessary to minimize voltage losses, especially at high load currents. The exact values of C1 and C2 are not critical but low ESR capacitors are necessary. The ESR of capacitor C1, the pump capacitor, can have a pronounced effect on the output. C1 currents are approximately twice the output current and losses occur on both the charge and discharge cycle. The ESR effects are thus multiplied by four. A 0.5 Ω ESR for C1 will have the same effect as a 2 Ω increase in CAT661 output impedance. Table 5. VRIPPLE vs. FOSC VRIPPLE (mV) 45 25 V+ I IOUT (mA) 100 100 Output voltage ripple is determined by the value of C2 and the load current. C2 is charged and discharged at a current roughly equal to the load current. The internal switching frequency is one−half the oscillator frequency.

It is recommended that before a design is finalized capacitor manufacturers should be surveyed for their latest product offerings. Controlling Loss in CAT661 Applications There are three primary sources of voltage loss: 1. Output resistance: VLOSS = ILOAD x ROUT, where ROUT is the CAT661 output resistance and ILOAD is the load current. 2. Charge pump (C1) capacitor ESR: VLOSSC1 ≈ 4 x ESRC1 x ILOAD, where ESRC1 is the ESR of capacitor C1. 3. Output or reservoir (C2) capacitor ESR: VLOSSC2 = ESRC2 x ILOAD, where ESRC2 is the ESR of capacitor C2. Increasing the value of C2 and/or decreasing its ESR will reduce noise and ripple. The effective output impedance of a CAT661 circuit is approximately: Rcircuit [ Rout 661 ) (4 ESRC1) ) ESRC2 http://onsemi.com 10 CAT661 Typical Applications Voltage Inversion Positive−to−Negative The CAT661 easily provides a negative supply voltage from a positive supply in the system.
