AP3602A 100mA REGULATED CHARGE PUMP Description Pin Assignments The AP3602A is a regulated step-up DC/DC converter based on (Top View) charge-pump technique. The chip has the ability to supply 100mA constant-output current or 250mA peak-output current for 100ms from Pin 1 Mark 3.0V to 5V input, so it can be used as a white LED driver or flash LED driver. + V 1 6 C OUT The AP3602A has very-low power dissipation and high efficiency in typical applications. Other features include overtemperature 5 V GND 2 IN protection and low-temperature coefficient to meet special requirements of handheld battery-powered devices. - SHDN 3 4 C Only three external capacitors are required in applications, which help save space and lower cost. The chip also has a disable terminal to (SOT26 (Type CJ)) turn on or turn off the chip to ease the use. The AP3602A is available in SOT26 (Type CJ) package. Applications Features Mobile Phone Backlight Driver Low-Quiescent Current: 13A Typical Camera Flash LED Driver Regulated Output Voltage Precision: 4% MP3, MP4 High-Output Current: 100mA when V 3.0V Handheld Device IN 50mA when V 2.7V Portable Communication Device IN High Frequency up to 1.2MHz Low Shutdown Supply Current: <1A High-Output Peak Current: 250mA for 100ms Overtemperature Protection Operating Temperature Range: -40C to +85C 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) & 2015/863/EU (RoHS 3) compliant. 2. See AP3602A Pin Descriptions Pin Number Package Name Function Regulated Output Voltage. V should be bypassed with a 1F to 22F low ESR ceramic OUT 1 V OUT capacitor, which is placed as close to the pin as possible for best performance Ground. GND should be tied to a ground plane for best performance. The C and C should OUT IN 2 GND be placed as close to this pin as possible Active Low Shutdown Input. A low signal on SHDN disables the AP3602A, while a high signal 3 SHDN enables the AP3602A. SHDN pin must not be allowed to float Flying Capacitor Negative Terminal. The flying capacitor should be placed as close to this pin 4 C as possible Input Supply Voltage. V should be bypassed with a 1F to 22F low ESR ceramic capacitor IN 5 V IN which is placed as close to the pin as possible for best performance Flying Capacitor Positive Terminal. The flying capacitor should be placed as close to this pin as + 6 C possible 2 of 11 August 2019 AP3602A Diodes Incorporated www.diodes.com Document number: DS36841 Rev. 4 - 2
