Product details
Overview
TEA1721BDB1065,598 from NXP is a GreenChip SMPS controller IC with integrated 700 V high-voltage MOSFET, designed for primary-side regulated flyback converters up to 5 W. It delivers <10 mW no-load power consumption, supports USB CC/CV charging, and eliminates optocouplers via primary-sensed voltage control - used in mobile USB chargers and smart meter power supplies.
For engineers reviewing the TEA1721BDB1065,598 datasheet, TEA1721BDB1065,598 pinout, TEA1721BDB1065,598 application, or TEA1721BDB1065,598 equivalent, key selection criteria include its SO7 package, 430 Hz burst frequency, 50.5 kHz max switching frequency, EEPROM-programmable burst modes, and compliance with Energy Star 2.0 and USB battery charging standards.
Technical Context
The TEA1721BDB1065,598 implements primary-side regulation using demagnetization detection and cable impedance compensation (0.3 Ω), enabling accurate CV/CC output without secondary feedback. Its architecture integrates active HV start-up, zero-current switching during normal operation, and soft-start via peak current reduction.
It operates in discontinuous conduction mode (DCM) with guaranteed demagnetization protection, includes OVP with auto-restart, UVLO with clamp, OTP, FB open/short protection, and jittering for EMI reduction - all while maintaining min fsw >22 kHz to avoid audible noise.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar SMPS controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TEA1721AT/N1,598 | No cable compensation (0 Ω); fixed 430 Hz burst; same SO7 package and 5 W rating. | Targeted at general-purpose adapters where USB cable drop is negligible or managed externally. | Select when cable compensation is unnecessary and BOM simplicity is prioritized over port-level CV accuracy. |
| MP172GJ-Z | Monolithic 650 V controller (no integrated MOSFET); requires external HV FET; supports up to 6 W. | Used where design flexibility (e.g., custom MOSFET selection) outweighs integration benefits. | Choose when thermal management or specific Rds(on) optimization demands discrete power switch implementation. |
Compared with TEA1721BDB1065,598, TEA1721AT/N1,598 offers identical topology support but lacks cable compensation - limiting USB port accuracy - while MP172GJ-Z trades integration for design flexibility, requiring external HV FET and increasing component count but enabling higher efficiency tuning.

FAQ
What is the maximum output power supported by the TEA1721BDB1065,598?
The TEA1721BDB1065,598 is rated for up to 5 W continuous output power in flyback configurations. This rating reflects its integrated 700 V MOSFET's safe operating area and thermal design envelope under typical ambient conditions. It is not rated for 11 W operation - that capability belongs to the TEA1723 variant. The 5 W limit ensures reliable DCM operation and compliance with no-load and efficiency targets.
Does the TEA1721BDB1065,598 support USB Battery Charging specification compliance?
Yes, the TEA1721BDB1065,598 supports USB Battery Charging (BC) 1.2 compliance through its built-in CC/CV control loop and cable impedance compensation. It delivers ±5% constant voltage and ±10% constant current accuracy at the USB port when configured per NXP application notes. This enables direct use in certified mobile USB chargers without secondary-side feedback components.
What package type and pin count does the TEA1721BDB1065,598 use?
The TEA1721BDB1065,598 uses a 7-pin SO (Small Outline) package with HV creepage spacing - designated SO7 in NXP documentation. All pins are surface-mount compatible, and the NC (no-connect) pin must remain unconnected. The package is halogen-free and RoHS compliant, meeting IPC/JEDEC J-STD-020 moisture sensitivity level 3.
How does the TEA1721BDB1065,598 achieve <10 mW no-load power consumption?
The TEA1721BDB1065,598 achieves <10 mW no-load power via integrated active HV start-up (eliminating bleeder resistors), burst-mode operation at 430 Hz, and ultra-low quiescent current in sleep state. Its architecture disables non-essential circuitry during light load, and the EEPROM-programmable burst frequency allows fine-tuning to minimize idle draw without sacrificing wake-up response time.
Is the TEA1721BDB1065,598 pin-compatible with other TEA172x variants like TEA1721AT/N1,598?
Yes, the TEA1721BDB1065,598 is pin-compatible with TEA1721AT/N1,598 and other SO7-packaged TEA1721 variants. All share identical pinout, package dimensions, and thermal pad configuration. However, internal EEPROM settings differ - specifically, TEA1721BDB1065,598 is programmed for 0.3 Ω cable compensation, whereas TEA1721AT/N1,598 defaults to 0 Ω. Firmware or hardware-level verification is required before substitution.
