Product details

Overview

TEA1610T/N5,118 from NXP Semiconductors is a high-voltage DMOS monolithic controller for zero-voltage-switching (ZVS) resonant half-bridge converters. It drives two external power MOSFETs, integrates a high-voltage level-shifter and bootstrap diode, provides latched shutdown for overcurrent/overvoltage protection, and delivers an accurate 50 % duty cycle via internal ÷2 flip-flop. It is used in TV and monitor power supplies operating across universal mains input.

For engineers reviewing the TEA1610T/N5,118 datasheet, TEA1610T/N5,118 pinout, TEA1610T/N5,118 application, or TEA1610T/N5,118 equivalent, this page delivers verified technical context, validated pin functions, confirmed ZVS resonant converter design parameters, and real-world alternative selection guidance - all grounded in the official NXP TEA1610T product data sheet Rev. 03 (2007).

Technical Context

The TEA1610T/N5,118 implements a current-controlled oscillator with externally programmable min/max frequency (188–550 kHz bridge range) via resistors R_f(min), R_∆f, and R_dt plus capacitor C_f. Its transconductance error amplifier (g_m = 330 µA/mV, V_CO output up to 4.0 V) regulates output voltage by modulating oscillator frequency, not duty cycle.

It features integrated high-side driver capability (±225 mA source/sink), undervoltage lockout (V_DD(start) = 13.4 V typ., hysteresis 4.0 V), and a latched shutdown input (V_SD(th) = 2.33 V) that clamps V_DD at 12.0 V during fault. The SO16 package supports compact layout with low stand-off height and 3.9 mm body width.

Key Specifications

I+ (Pin 2)	Error amplifier non-inverting input	Reference node for regulation; typically tied to VREF (3.0 V) or precision reference for tracking designs.
VCO (Pin 3)	Error amplifier output	Current-source output driving IRS pin; frequency modulation signal for oscillator control loop.
PGND (Pin 4)	Power ground	Return path for high-current gate drivers; must be separated from SGND to minimize noise coupling.
n.c. (Pin 5)	Not connected	High-voltage spacer; no internal connection; must remain unconnected and isolated.
SH (Pin 6)	High-side switch source	Connects directly to source of high-side MOSFET; serves as floating reference for GH and VDD(F).

SGND (Pin 9)	Signal ground	Reference for low-side driver, oscillator, error amp, and logic; must be routed separately from PGND.
GL (Pin 10)	Low-side gate driver output	Drives gate of low-side MOSFET; referenced to SGND; ±225 mA drive capability.
VDD (Pin 11)	Main supply voltage	Input for internal logic and low-side driver; requires local 100 nF decoupling per datasheet recommendation.
IFS (Pin 12)	Oscillator discharge current input	Sets falling slope of oscillator sawtooth and determines dead time via external R_dt.
CF (Pin 13)	Oscillator timing capacitor	External capacitor (e.g., 100–220 pF) setting oscillator ramp time; critical for frequency accuracy and stability.
IRS (Pin 14)	Oscillator charge current input	Sets rising slope of oscillator sawtooth; combined with IFS and CF to define min/max frequency range.
SD (Pin 15)	Shut-down input	Active-high latch input; triggers immediate gate turn-off and VDD clamp at 12.0 V when ≥2.33 V applied.
VREF (Pin 16)	3.0 V reference voltage	Stable, temperature-compensated reference (±0.1 V) for feedback and oscillator biasing; capable of sourcing −1.0 mA.

Equivalent & Alternatives

The following parts are listed as comparable options for similar zero-voltage-switching resonant converter controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
UCC256301DR	Integrated 600 V high-side driver, digital frequency control, no external CF/IRS/IFS pins; requires MCU configuration.	Targets digitally programmable, feature-rich ZVS platforms; lacks analog tuning flexibility of TEA1610T/N5,118.	Choose UCC256301DR for designs needing soft-start profiles, burst mode, or firmware-based protection sequencing.
ICE2PCS01G	Analog PFC + resonant LLC controller combo; single-chip solution with integrated 650 V MOSFET driver; no separate high-side level shifter.	Designed for combined PFC + resonant DC-DC stages; not suitable for standalone half-bridge ZVS without PFC stage.	Choose ICE2PCS01G only when both active PFC and resonant conversion are required in one IC; not a drop-in replacement.

Compared with UCC256301DR and ICE2PCS01G, the TEA1610T/N5,118 offers unmatched analog configurability for ZVS half-bridge tuning - including independent dead time, min/max frequency, and bootstrap timing - without firmware dependency or PFC integration overhead.

FAQ

What is the primary function of the TEA1610T/N5,118 in a power supply design?

The TEA1610T/N5,118 serves as a dedicated zero-voltage-switching (ZVS) resonant half-bridge controller. It drives two external power MOSFETs, manages frequency-based output regulation via its transconductance error amplifier, and integrates high-voltage level-shifting and bootstrap functionality - all essential for efficient, low-noise AC-DC conversion in TV and monitor power supplies. Its core purpose is to enable ZVS operation without requiring external level-shifters or complex timing ICs.

How does the TEA1610T/N5,118 achieve accurate 50 % duty cycle control?

The TEA1610T/N5,118 achieves accurate 50 % duty cycle by routing its internal oscillator signal through a divide-by-two flip-flop before delivering it to the high- and low-side output drivers. This hardware-based division guarantees exact symmetry regardless of oscillator frequency drift, component tolerances, or temperature variation - eliminating the need for external duty-cycle correction circuitry and ensuring consistent ZVS timing across operating conditions.

Can the TEA1610T/N5,118 operate without an external bootstrap capacitor?

No, the TEA1610T/N5,118 requires an external bootstrap capacitor connected between VDD(F) and SH pins to power the high-side gate driver. The IC integrates a bootstrap diode but does not include the storage capacitor. Datasheet Figure 10 specifies a typical 100 nF ceramic capacitor placed close to the VDD pin for stable operation, and omission results in failure of high-side switching and potential latch-up.

What is the role of the n.c. (Pin 5) on the TEA1610T/N5,118?

Pin 5 on the TEA1610T/N5,118 is explicitly designated "not connected" and functions as a high-voltage spacer. It has no internal connection and must remain unconnected and electrically isolated in PCB layout. Its presence maintains safe creepage/clearance distances between adjacent high-voltage pins (e.g., SH and GH), supporting reliable operation at up to 600 V common-mode voltage - a requirement confirmed in the official NXP pin description table.

How is overvoltage protection implemented using the TEA1610T/N5,118?

Overvoltage protection is implemented using the TEA1610T/N5,118's dedicated shut-down (SD) input (Pin 15). A resistor divider from the regulated output to SD triggers shutdown when voltage exceeds 2.33 V (±70 mV). Upon activation, both gate drivers disable immediately and VDD is clamped internally at 12.0 V, preventing further switching until VDD drops below 5.3 V to reset the latch - providing robust, self-contained OVP without external comparators or timers.
