The APL5610/A could drive an external N-Channel MOSFET and provides an adjustable output by using an external resistive divider. The APL5610/A integrates various functions. For example, a Power-On-Reset (POR) circuit monitors VCC supply voltage to prevent wrong operations; the function of Under-Voltage Protection (UVP) protects the device from short circuit condition. A POK indicates that the output status with time delay which is set internally. It can control other converter for power sequence. Moreover, the APL5610/A can be enabled by other power system; namely, holding the EN above 1.6V enables output and pulling the EN under 0.4 disables output. The APL5610/A is available in SOT-23-6 package. • • SOT-23-6 Package Lead Free and Green Devices Available (RoHS Compliant) Simplified Application Circuit VCC VIN ON EN EN VCC DRV Applications • • Note Book PC Applications Motherboard Applications OFF Pin Configuration APL5610/A EN 1 GND 2 FB 3 SOT-23-6 (Top View) 6 VCC 5 DRV 4 POK APL5610 APL5610A POK POK GND FB VOUT - ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and advise customers to obtain the latest version of relevant information to verify before placing orders.

Package Thermal Resistance θ(JA): Select a package of MOSFET that can dissipate the heat, θ(JA) < (TJ – TA)/PD, where TJ is the maximum allowable Junction temperature of MOSFET, TA is the ambient temperature, PD is the maximum power dissipation on MOSFET, calculated as below: PD =(VIN(max) – VOUT(min)) x IOUT(max) Power Sequencing (Only for APL5610A) At start-up, it is necessary to ensure that the VIN (the voltage supplied to MOSFET drain), VCC and V EN a re sequenced correctly to avoid erroneous latch-off. To avoid UVP latch-off happened at start-up due to sequencing issues, the key method is the VIN should be larger than the output under-voltage threshold plus the drop through the pass MOSFET when that output is enabled. Figure 1 and 2 show the two types of power on sequence. Figure 1 shows the VCC comes up before the VIN, and then the output would be enabled when the VEN is applied. Figure 2 shows the VIN comes up before the VCC, and then the output can either be enabled with the VCC or VEN. Recommended power on sequence is shown in Figure1 and 2. MOSFET Selection APL5610/A requires an N-channel MOSFET as a pass element. There are some parameters must be considered in selecting a MOFSET, including: Threshold Voltage VTH, RDS(on ), Continuous IDS current and Package Thermal Resistance. The MOSFET selection guidelines are listed as below: 1. Threshold Voltage VTH: Select the MOSFET VTH rating to meet the following equation: VTH < VCC(min) – VOUT(max) VIN VUV(TH) VEN(TH) VEN VOUT VEN(TH) occurs after VUV(TH) is reached Figure 1.

MOSFET drain supply comes up before APL5610A supply Short Circuit Concerns (Only for APL5610) R2 COUT Load Figure 3 Since the APL5610 UVP function is activated after the VOUT reaches 90% level, any combinations of sequence among VIN, VCC, and VEN are allowable. However, please note that the advantage of none-power-sequencing brings a drawback. If and only if a short circuit condition of output voltage occurs before VIN supply, the UVP won’ be t activated. Thus, the short circuit current persists to flow and could impair the MOSFET. If in your application the short circuit is most likely to be encountered before VIN supply, we suggest you use the APL5610A instead of the APL5610, who can provide this short circuit protection. Nevertheless, if the V IN s upply can provide the OCP protection, this short circuit won’ be an issue in APL5610. t Layout Consideration Figure 3 illustrates the layout. Below is a checklist for your layout: 1. Please place the input capacitor CVCC close to the VCC pin. 2. Please place the CVIN close to the MOSFET’ drain. s 3. Layout a copper plane for N-channel MOSFET’ drain s to improve the heat dissipation. 4. Output capacitor COUT for load must be placed near the load as close as possible. 5. Large current paths, the bold lines in figure 3, must have wide tracks. C opyright © A NPEC Electronics Corp. Rev.
