A Product Line of Diodes Incorporated AP4310A DUAL OP AMP AND VOLTAGE REFERENCE Description Pin Assignments
The AP4310A is a monolithic IC specifically designed to regulate the output current and voltage levels of switching battery chargers and power supplies
(Top View)
The device contains two Op Amps and a 2.5V precision shunt voltage reference. Op Amp 1 is designed for voltage control with its non- inverting input internally connected to the output of the shunt OUTPUT 1 1 8 VCC regulator. Op Amp 2 is for current control with both inputs uncommitted. The IC offers the power converter designer a control INPUT 1- 2 7 OUTPUT 2 solution that features increased precision with a corresponding reduction in system complexity and cost. INPUT 1+/VKA 3 6 INPUT 2- The AP4310A is available in SO-8 package. GND 4 5 INPUT 2+
Features SO-8 OP Amp
Input Offset Voltage: 0.5mV Supply Current: 75A per OP Amp at 5.0V Supply Voltage
Applications
Unity Gain Bandwidth:1MHz Output Voltage Swing: 0 to V Battery Charger CC-1.5V Power Supply Range: 3 to 36V Switching Power Supply
Voltage Reference
Fixed Output Voltage Reference: 2.5V Reference Voltage Tolerance :±0.4% Sink Current Capability: 0.05 to 80mA Typical Output Impedance: 0.2Ω
Totally Lead-free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. “Green” Device (Note 3)
Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant. 2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free. 3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm antimony compounds.
Typical Applications Circuit
