Typical Applications
IRS2153DSPBF is suitable for 6 applications: Fluorescent & HID Electronic Ballast, Half-Bridge Switch-Mode Power Supply, Motor Drive Front-End (Low-Voltage BLDC/PMSM), Electronic Transformer for Low-Voltage Halogen Lamps, Auxiliary Power Supply for Industrial Equipment, LED Driver Front-End (AC-DC Stage).
Fluorescent & HID Electronic Ballast
The IRS2153DSPBF's self-oscillating RC network is purpose-built for fluorescent and HID electronic ballasts, where the driver replaces a discrete 555 timer + optocoupler + level shifter with a single 8-SOIC part. Its 600V offset rating directly supports rectified 230V mains with adequate margin, while the ~1.2 us internal deadtime prevents shoot-through in the half-bridge during lamp startup transients. Compared to a discrete implementation, the IRS2153DSPBF reduces BOM count by ~6 components, improves reliability through integrated HVIC latch-immune CMOS, and provides automatic restart via VCC UVLO. Designers typically program the oscillator to 30-50 kHz and add a PTC / thermistor network for lamp preheat.
Recommended
Half-Bridge Switch-Mode Power Supply
In hard-switched half-bridge converters up to ~500W, the IRS2153DSPBF drives the two primary-side MOSFETs with 130 mA source / 270 mA sink gate-drive current - sufficient for medium-power MOSFETs with Qg up to ~30 nC. The driver's self-oscillating behavior is acceptable for fixed-frequency or open-loop converters (e.g., lamp ballasts, simple chargers), and its 600V rating supports universal-input designs. The 8-SOIC package enables compact PCB layouts where the half-bridge fits beneath the transformer bobbin. For closed-loop control, pair with an external PWM controller on the secondary-side feedback path.
Recommended
Motor Drive Front-End (Low-Voltage BLDC/PMSM)
The IRS2153DSPBF can drive a half-bridge leg in a low-voltage three-phase BLDC or PMSM motor inverter when combined with external commutation logic. Its 600V rating provides huge headroom for 24V, 48V, and even 400V bus rails, and the 130/270 mA drive current is sufficient for IGBTs and medium-FOM MOSFETs. The 8-SOIC footprint allows placement near each phase leg for minimal gate-loop inductance. Designers should add external shoot-through protection logic and a three-phase controller IC for full three-phase operation - the IRS2153DSPBF is a single half-bridge driver, not a 3-phase pre-driver.
Recommended
Electronic Transformer for Low-Voltage Halogen Lamps
The IRS2153DSPBF is a near-ideal controller for 12V electronic halogen transformers, where the half-bridge topology at 30-50 kHz replaces the mains-frequency iron-core transformer. The driver's 600V offset handles rectified 230V mains directly, and its self-oscillating behavior eliminates the need for a separate controller IC - reducing total BOM cost in price-sensitive lighting products. The 8-SOIC package and low quiescent current support compact, low-cost PCB layouts that fit inside the lamp base. Output short-circuit protection can be added externally by sensing primary current and pulling the RT/CT pin high.
Recommended
Auxiliary Power Supply for Industrial Equipment
For auxiliary / standby power supplies in industrial PLCs, motor drives, and HVAC controllers, the IRS2153DSPBF delivers a self-oscillating half-bridge converter at low cost. Its 10-20V VCC range is compatible with standard 12V and 15V auxiliary rails, and the 600V offset rating supports both 230V and 400V industrial mains. The driver's latch-immune CMOS construction provides excellent noise immunity in electrically harsh industrial environments, and the integrated UVLO prevents erratic startup under slow-rising bus voltages. The 8-SOIC package is pin-compatible with the IR2153 family, allowing drop-in modernization of legacy designs.
Recommended
LED Driver Front-End (AC-DC Stage)
In two-stage AC-DC LED drivers, the IRS2153DSPBF serves as the PFC or front-end half-bridge converter controller, providing an isolated DC bus that feeds a downstream buck or constant-current stage. Its self-oscillating behavior is acceptable for fixed-frequency open-loop front ends, and the 600V rating supports universal-input designs up to ~277V AC. The 130/270 mA gate-drive current can switch MOSFETs up to ~600V / 10A, making it suitable for 50-150W LED luminaires. Designers can disable the oscillator at light load via the RT/CT pin to meet efficiency regulations.

- Higher 600V voltage rating than IRS2008STRPBF (vs IRS2008STRPBF)
Design Notes
Bootstrap capacitor sizing: choose CBOOT so that VBS remains above the UVLO turn-off threshold during the high-side on-time. A common starting point is CBOOT >= Qg_total / deltaVBS, where deltaVBS is the allowable droop (typically 0.5-1V). For 30 kHz operation with 30 nC Qg MOSFETs and 100 ns high-side on-time, a 100 nF ceramic bootstrap capacitor is usually sufficient. Add a 100 ohm resistor in series with the bootstrap diode to limit inrush current during the low-side refresh pulse.
Minimize the high-side gate-drive loop: place the bootstrap capacitor and diode as close to pins 6 (VS) and 8 (VB) as possible, and keep the gate-drive traces short and wide. The high-side gate return (VS) carries the full switching-node dV/dt - any inductance here couples into the gate drive and can cause spurious turn-on. Use a ground plane on the bottom layer and avoid routing sensitive analog signals (RT/CT) across the switching node.
At low switching frequencies (30-50 kHz) and modest gate-drive currents (130/270 mA), the IRS2153DSPBF dissipates well under 100 mW and requires no heatsink. However, in deadtime-loss-dominated designs or at higher switching frequencies, the gate-drive dissipation PD = Qg * VCC * fSW can become significant - for 30 nC Qg at 100 kHz with 15V VCC, PD = 45 mW per channel. Keep the SOIC-8 ground pad soldered to a continuous ground pour for thermal spreading, even though the thermal pad is not formally specified in all datasheets.
Do not exceed VBS-VS = 20V (the bootstrap supply absolute maximum) - place a 15V Zener or TVS diode across the bootstrap capacitor if there is any risk of over-voltage during start-up or short-circuit events. Also, the RT/CT pin is a sensitive analog node; keep the timing components physically close to pin 2 and use a ground-return trace that does not share copper with switching currents. Finally, verify that VCC rises above the UVLO turn-on threshold (typically 8V) before drawing load current, or the driver may exhibit half-bridge shoot-through.
