Typical Applications
IRS2153DSTRPBF is suitable for 6 applications: Fluorescent and HID Electronic Ballasts, Induction Heating Cooktops, Low-Power Half-Bridge SMPS, DC-AC Inverters for Solar and UPS, Electronic Transformers for Halogen Lighting, Auxiliary Power Supplies in Motor Drives.
Fluorescent and HID Electronic Ballasts
The IRS2153DSTRPBF's integrated RC oscillator makes it ideally suited for driving the half-bridge output stage of fluorescent-tube and high-intensity-discharge (HID) lamp ballasts. With 600 V high-side floating supply capability and 0.18 A source / 0.26 A sink drive currents, it directly switches 600 V-class MOSFETs on the high-side and low-side of the lamp resonant tank. RT and CT program the operating frequency (typically 30-100 kHz) for resonant ignition, and the integrated bootstrap FET eliminates the external bootstrap diode, reducing the BOM. Designers benefit from the self-oscillating topology because no separate controller IC or PFC front end is required for cost-sensitive ballast designs.
Recommended
Induction Heating Cooktops
Induction-heating cooktops require a half-bridge or quasi-resonant inverter operating at 20-100 kHz to drive the induction coil. The IRS2153DSTRPBF is a strong fit because its internal 555-style oscillator combined with the programmable shutdown pin allows the cooktop controller to gate operation on/off while leaving the power-stage timing autonomous. The 1.1 us typical propagation delay supports clean switching transitions at typical induction-heating frequencies, and the 600 V VB rating tolerates the rectified 220 V or 380 V mains bus. The integrated bootstrap FET simplifies PCB layout in cooktop designs where compactness and thermal management are critical.
Recommended
Low-Power Half-Bridge SMPS
Off-line half-bridge switch-mode power supplies (SMPS) under 300 W often use a self-oscillating driver to reduce controller cost. The IRS2153DSTRPBF replaces a discrete oscillator plus driver pair with a single 8-pin SOIC, driving the primary-side half-bridge MOSFETs from a 12-15 V auxiliary winding. The 600 V floating supply rating suits universal-input (85-265 VAC) designs after rectification to 400 VDC bus. Designers use the SD pin as an under-voltage-lockout (UVLO) or overload-shutdown input by connecting it to a voltage divider on the auxiliary rail. The integrated bootstrap FET and minimal external component count shorten design-in time versus discrete solutions.
Recommended
DC-AC Inverters for Solar and UPS
Low-cost DC-to-AC inverter stages (e.g., 12 V/24 V battery to 220 VAC) for solar micro-inverters or uninterruptible power supplies (UPS) often use a self-oscillating half-bridge as the DC-AC switching stage. The IRS2153DSTRPBF drives the half-bridge MOSFETs from a self-generated oscillator, allowing the inverter to operate without a dedicated microcontroller. Its 600 V VB rating supports 220 VAC line outputs, and the 0.26 A sink current is sufficient for switching the 500 V-class MOSFETs commonly used in sub-1 kW micro-inverter designs. The shutdown pin can be used for battery under-voltage cutoff protection, increasing system safety.
Recommended
Electronic Transformers for Halogen Lighting
Electronic transformers that drive 12 V halogen lamps from 220 VAC mains typically use a self-oscillating Royer or half-bridge topology operating at 30-50 kHz. The IRS2153DSTRPBF is a drop-in choice because its RC-oscillator timing naturally suits Royer-class converters, and the 600 V half-bridge rating tolerates the rectified 220 V bus. The integrated shutdown pin allows simple over-temperature protection by connecting an NTC thermistor network. The SOIC-8 footprint keeps the transformer module compact, which is critical for fitting the driver and MOSFETs inside a small halogen-lamp housing.
Recommended
Auxiliary Power Supplies in Motor Drives
Industrial motor drives frequently require a small auxiliary supply (15-24 V, 5-20 W) for gate-driver bias rails and control electronics. The IRS2153DSTRPBF can serve as the heart of a small half-bridge flyback or push-pull converter that derives an isolated auxiliary rail from the DC bus. Its self-oscillating topology eliminates the need for a dedicated PWM controller, reducing cost and complexity. The 600 V high-side rating and integrated bootstrap FET are particularly useful when the auxiliary supply must operate directly off the rectified 400 V or 800 V DC bus, simplifying the auxiliary power architecture in three-phase motor-drive designs.

Design Notes
Estimated: The IRS2153DSTRPBF quiescent current (IDD) is in the low milliamp range per the datasheet. VCC should be derived from an auxiliary winding or a small linear regulator. Add a 10 uF + 0.1 uF decoupling capacitor pair directly on the VCC pin to suppress noise. The VCC supply voltage range is 10 V to 20 V with UVLO turn-on at approximately 8 V - ensure the auxiliary winding produces >10 V at minimum load.
The 8-pin SOIC has a theta_JA of approximately 150 C/W on a standard JEDEC 2s2p board. With a quiescent current of a few mA and intermittent switching losses, the part typically dissipates well under 0.5 W. However, if VCC is shorted to ground or sustained shoot-through occurs, the device can dissipate several watts. For designs operating near 100 kHz with high gate-charge MOSFETs, verify junction temperature rise on the bench using a thermal camera.
Place RT and CT as close as possible to pins 2 and 3 with short trace lengths to minimize parasitic capacitance that would shift the oscillator frequency. Keep the CT node away from the HO and VS switching nodes to prevent false triggering. The bootstrap capacitor (typically 0.1 uF to 1 uF) and optional series bootstrap resistor should be placed close to pins 7 (VS) and 8 (HO). Use a ground plane on the COM pin side to reduce ground bounce during switching transitions.
Do not exceed the 600 V VB-VS maximum. When designing for 220 VAC rectified mains (400 VDC bus plus ringing), allow at least 50 V margin. The SD pin is referenced to COM and should not be left floating - tie it to VCC through a 10 kO resistor if shutdown control is not needed. Ensure the high-side bootstrap capacitor has sufficient charge time at the minimum programmed frequency to refresh VBS above the undervoltage threshold, otherwise the high-side output will intermittently drop out.
