说明

ADM660ARZ-REEL7 Overview

The ADM660ARZ-REEL7 is a CMOS switched-capacitor voltage converter (charge pump) from Analog Devices, supply voltage 1.5V-5.5V, supporting voltage inversion or doubling, 100mA output current, up to 99% efficiency, in an SOIC-8 package.

主要功能

  • Supply voltage: 1.5V-5.5V
  • Output current: 100mA
  • Voltage inversion or doubling
  • Oscillator frequency: 25kHz/120kHz selectable
  • Efficiency up to 99%
  • On-resistance: 9 Ohm

The ADM660ARZ-REEL7 is a CMOS switched-capacitor voltage converter from Analog Devices, capable of inverting an input voltage from +1.5 V to +7 V or doubling it, delivering up to 100 mA output current. In inverting mode, it generates a negative supply from a positive input, while in doubling mode it can produce up to 14 V from a 7 V input. The SOIC-8 package includes a frequency control (FC) pin to select between 25 kHz for low-noise operation and 120 kHz for smaller capacitor size, requiring only 10 uF or 2.2 uF external capacitors respectively.

The ADM660ARZ-REEL7 operates as a switched-capacitor charge pump using a two-phase clock. During Phase 1, an internal MOSFET switch connects the flying capacitor (C1) between VIN and ground, charging it to the input voltage. During Phase 2, the switch reconnects C1 between ground and the output, transferring its charge to the output capacitor (C2). In inverter mode, the output capacitor is connected with opposite polarity, generating a negative voltage equal to -VIN. In doubler mode, the flying capacitor is stacked on top of the input voltage, producing approximately 2 x VIN at the output. The FC pin selects the internal oscillator frequency: 25 kHz (FC low or open) or 120 kHz (FC connected to LV), allowing trade-off between capacitor size and output ripple. The LV (Low Voltage) pin enables operation down to 1.5 V input.

针脚 名称 说明
1 LV Low voltage enable; connect to GND for VIN below 3 V, leave open for VIN above 3 V
2 OSC Oscillator input; connect external capacitor to reduce frequency or drive with external clock
3 VOUT Negative output voltage (inverter mode) or doubled output (doubler mode)
4 接地 地面参考
5 CAP+ Positive terminal of flying capacitor C1
6 CAP- Negative terminal of flying capacitor C1
7 OSC2 Oscillator output (internal clock); leave open for normal operation
8 VIN Positive supply input (+1.5 V to +7 V)
  • Negative Rail Generation: Creating -5 V or -12 V from a positive supply for op-amp biasing in single-supply systems
  • Display LCD Bias: Inverting supply for contrast adjustment in LCD modules
  • Portable Instrumentation: Dual-rail analog front-end supply from a single battery
  • RS-232 Transceivers: Generating the negative supply required by RS-232 line drivers
  • Voltage Doubling: Boosting 3.3 V or 5 V logic rails to 6.6 V or 10 V for gate drive
模型 制造商 VIN Iout 包装 说明
ICL7660 瑞萨 1.5-10 V 20 mA SOIC-8 Lower cost, lower current
MAX660 马克西姆 1.5-5.5 V 100 mA SOIC-8 Pin-compatible, higher freq
LM2662 德州仪器 1.5-5.5 V 200 mA SOIC-8 Higher output current
ADM8660 模拟器件公司 1.5-7 V 100 mA SOIC-8 Shutdown feature added
TPS60400 德州仪器 1.6-5.5 V 60 mA SOT-23 Ultra-small package

ADM660ARZ-REEL7 is a CMOS charge pump from ADI in SOIC-8. The ADM8660ARZ adds a shutdown pin for power conservation. The ICL7660S from Renesas/Intersil provides the same inverting/doubling function with enhanced ESD. The MAX660 from Maxim offers 100mA output current with selectable oscillator frequency. The LT1054 from ADI provides higher 100mA output with regulation capability. For smaller footprint, LM27761 provides 250mA regulated inverting output in DSBGA-8.
